Research Interests

Dr Mathe鈥檚 research interest is in the photoluminescence studies, focussing on the effects of incorporating anions, such as (BO33-, PO43-, SO42- ) on the photoluminescence properties of Yttrium Oxide (Y2O3), doped and co-doped with rare-earth ions (Eu3+, Er3+, Yb3+/Eu3+ and Yb3+/Er3+). In our research, the latter is done via down- and up-conversion schemes, respectively. Our research demonstrates听 that when anions are incorporated on the nanophosphors, photoluminescence characteristics are enhanced. The tuning of the concentration of the dopants and co-dopants also play a role in improving the colour purity of the nanophosphors. The aim is to patent these nanophosphors and use them in colour display systems for commercial and industrial applications.
