Prof Hendrik Swart
Prof Hendrik Swart from the UFS Department of Physics was recently recognised by the Golden Key Honour Society Southern Africa as one of South Africa’s 300 most influential leaders.

Prof Hendrik Swart from the University of the Free State (UFS) Department of Physics was recently honoured at the Golden Key Honour Society Southern Africa’s Black Tie Gala Event, held on 23 May 2025. The event celebrated 300 of South Africa’s most influential leaders across academia, industry, government, and the financial sector.

Prof Swart, who is an NRF B1-rated researcher and currently also holds the SARChI Research Chair in Solid-state Luminescent and Advanced Materials (2023-2027), described the recognition as both meaningful and affirming at this stage of his academic journey.

“Being recognised by such a prestigious organisation is a meaningful acknowledgment of my academic efforts and personal dedication,” he says. “It was a moment of validation and inspiration, reminding me that hard work truly pays off.”

While the exact selection criteria were not publicly detailed, the emphasis was placed on academic excellence, scholarship, and leadership.

This is not Prof Swart’s first recognition from the Golden Key Honour Society. In 2012, the UFS student chapter awarded him honorary membership for his contributions as a mentor and supervisor – an early nod to his lasting impact on student success.

“The student chapter here on campus gave me some recognition by awarding me honorary membership,” he recalled. “It meant a lot to me as a mentor.”

The gala itself offered more than accolades – it created a space for meaningful exchange. Prof Swart reflected warmly on reconnecting with one of his former students from the early 2000s, calling it a highlight of the evening.

Looking ahead, Prof Swart welcomed the society’s plans to continue this initiative across the country.

“This was the first time they had an event like this, but more are expected to follow. I see it as a good initiative to mingle with other sectors in South Africa.”

UFS involved in project to light up the townships

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships   

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.   

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens.  The red, green and blue spots on the television screens originate from these kinds of phosphor materials.  “At that stage plasma television screens were only a dream.  Today it is sold everywhere,” said Prof Swart. 

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material.  We also started to concentrate on the effectiveness of nano phosphors.  In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre.  These particles can provide light as soon as they are illuminated with, for instance, sunlight.  The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials.  Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.   

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.  

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project.  The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited.  “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years.  “During this time we want to determine how the effectiveness of the phosphors can be increased.  Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
