Prof. Dr. Cees Ronda studied inorganic and theoretical chemistry at the State University of Groningen, the Netherlands. He also obtained his Ph-D from this University. His research dealt with optical absorption, magnetic susceptibility, and MCD spectroscopy on giant magnetic spin clusters in MnI2:Ni and in charge density waves in (V,Cr)Se2. In addition, he worked on luminescence, photoconductivity and photographic phenomena in some layered metal dihalides.
After obtaining his Ph-D, he joined Philips Research, where he has been working on luminescent materials, water- and air purification, sensors and oral health care solutions. One of the results obtained was the clarification of the luminescence mechanism operating in Zn2SiO4: , that turned out the be exchange induced. The influence of magnetic interactions on the luminescence of Ce3+ in some garnets was studied as well.
Cees Ronda was a professor at Utrecht University, the Netherlands (optical materials) and Zhejiang University, Hangzhou, China (optical Physics). While at Philips, he was also responsible for large co-operations in Russia and China.
