Other
My research is focused on the development of rare-earth free inorganic nanomaterials for phosphor converted white LEDs (pc-WLEDs) and biological imaging applications. I develop these materials though the incorporation of a transition metal into an alkaline earth matrix and perform shape modulation from 0D to 3D particle shapes, by varying different parameters using hydrothermal synthesis method. To better understand and improve the structural and optical properties of these materials, I make use of sophisticated microscopic and spectroscopic techniques. I also use Thermoluminescence technique to check their possible applications in persistent luminescence.
