Luminescent Nanomaterials

Odireleng Martin Ntwaeaborwa is a professor of physics at the University of the Witwatersrand, South Africa. He received his PhD from the University of the Free State, South Africa, in 2006. He has served the South African Nanotechnology Initiative (SANi) in many capacities, including being its president in 2012–2016. He was a deputy dean of the Southern African Young Scientists Summer Program in 2012–2015 that was co-organized by the government of South Africa and the International Institute of Applied Systems Analysis (IIASA). He was a director of the UNESCO-TWAS Centre of Excellence for the advancement of science in developing countries in 2012–2016. He has received numerous awards, including Research Excellence Award from the University of the Free State, Young Investigator Award from the South African National Science and Technology Forum, and Young Investigator Award from the American Vacuum Society. He has published more than 260 articles, over 100 conference proceedings, and 7 book chapters. His research interests are surface science, powders and thin films of optoelectronics nanomaterials applied to displays, solid-state lighting, solar cells, and gas sensors.
