Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey.

The University of the Free State (UFS) is celebrating Youth Month by showcasing the positive influence of the institution on career development. As part of this initiative, we are sharing the stories of UFS alumni who are now working at the university.

Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics, shares his UFS journey:

Q: Year of graduation from the UFS: 

A: 2004 and 2015.

Q: Qualification obtained from the UFS: 

A: BSc in Physics and Mathematics and PhD in Solid State Physics.

Q: Date of joining the UFS as a staff member: 

A: 2003 to 2004 and 2012 to date.

Q: Initial job title and current job title: 

A: I began my journey as a Lab Assistant, but over time, I advanced to higher positions within the academic realm. Presently, I proudly serve as a Senior Lecturer and Subject Head in the esteemed Department of Physics. Additionally, I have taken on the role of acting Assistant Dean in the distinguished Faculty of Natural and Agricultural Sciences.

Q: How did the UFS prepare you for the professional world? 

A: First and foremost, I successfully completed my BSc degree, followed by the attainment of a Doctor of Philosophy (PhD). I firmly believe that these educational achievements serve as a solid foundation for excelling in both teaching and leadership roles.

Q: What are your thoughts on transitioning from a UFS alumnus to a staff member? 

A: It is a very interesting aspect; however, this transition may entirely depend on an individual’s interest in whether to continue with their studies or not. The stimulation may come from the undergraduate teachings that exhibit real interventions for new developments towards empowering the society at large.

Q: Any additional comments about your experience? 
A: As both an academic and a departmental leader for the past nine years, I am very grateful for all the support from the university community. I would encourage young scholars to explore more leadership roles that are available in the sector, because one is always up to date with new initiatives and strategies for the betterment of human and academic projects.

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.
