Prof Stef Coetzee, former Rector and Vice-Chancellor of the University of the Free State (UFS), passed away in the Mediclinic Cape Gate on Saturday 27 October 2018.
Prof Coetzee assumed duty as the 11th Rector and Vice-Chancellor of the UFS on 1 April 1997. He will be remembered for his drive to promote transformation at the UFS. During his time as Rector and Vice-Chancellor, he initiated a revitalisation process (turnaround strategy) which was ultimately finalised by his successor, Prof Frederick Fourie.
Among others, he established a Broad Transformation Forum (BTF) and transformation office to draft a new political framework for the UFS. He strived to manage the university as a business enterprise and was focused on developing the academy in an entrepreneurial manner. His legacy includes the establishment of the BTF, the revitalisation process (turnaround strategy), academic revitalisation, growing student numbers, and increased research outputs. He stepped down as Rector at the end of 2002.
“The turnaround strategy initiated by Prof Coetzee during his term as Rector and Vice-Chancellor is still evident today in the management approach of the UFS. On behalf of the executive management and the university community, I wish his family, relatives, and former colleagues all the best during this difficult and sad time. I hope that they will find comfort in his significant contribution to various sectors in the country – especially at the UFS,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.
Prof Stef Coetzee obtained his MA degree in Economics at Stellenbosch University in 1973, and a DPhil in Development Economics at the University of the Free State (UFS) in 1980. He is a former Executive Officer of the Afrikaanse Handelsinstituut and was also associated with Unisa and the North-West University.

A research project into low-energy lighting using phosphor materials for light emitting diodes (LEDs) at the Department of Physics at the University of the Free State (UFS) has received further recognition.
The South African Research Chairs Initiative (SARChi) has awarded further funding for the Research Chair in Solid State Luminescent and Advanced Materials situated in the department. Prof Hendrik Swart, a Senior Research Professor in the Department of Physics, says this means that the Chair will carry on receiving funds from SARChi for another five years. The Initiative also awarded Prof Swart in 2012 for the research, which resulted in funding for equipment and among others, bursaries.
Better light emission in LED’s
The research focuses on better light emission of phosphor powers in LEDs. It is also looking into improving LED displays in flat screens. The research into solar cells has shown that phosphors can also increase their efficiency by increasing the range of light frequencies, which convert into electricity. It also entails that glow-in-the-dark coatings absorb light during the day and emit it at night.
Prof Swart says over the next five years the research will focus on developing and producing devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have.” In practical terms, it means they want a farmer’s water pump that works with solar energy to work better with less energy input.”
Device that simulates sunlight
Prof Swart says the renewal of the Chair’s funding means the department can now get equipment to enhance its research such as a solar simulator. The solar simulator uses white LEDs whose intensity output and wavelengths can be tuned. The output is measured in number of suns. It enables researchers to work in a laboratory with a device that simulates sunlight.
According to Prof Swart the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field.
About 10 postdoctoral researchers are working on the studies done by the Chair in collaboration with the Council for Scientific and Industrial Research.
The Research Chair Initiative aims to improve the research capacity at public universities to produce high-quality postgraduate students, research and innovative outputs. The criterion for evaluating the department’s Chair includes aspects such as how much development has occurred over the past five years. The assessors look at features such as the number of students the research entity has trained and how many publications the research team has produced.
