Rajesh Dagupati received his PhD degree (2014) in Solid State Spectroscopy from the Sri Venkateswara University, Tirupati, Andhra Pradesh, India. The title of his PhD thesis was “Concentration effect on Spectroscopic Properties of Different Rare Earth ions doped Strontium-Lithium-Bismuth-Borate glasses. From October 2015 to July 2017, he was a postdoctoral fellow in Magnetic Resonance Group, is a part of CeRTEV (Center for Research, Technology and Education in Vitreous Martials), at Physics Institute of Sao Carlos, Sao Paulo University, Sao Carlos, Brazil. During this period, he worked on synthesis of oxyfluro Tellurite glasses and transparent glass ceramics doped with rare earth ions and metal nano particles for solar energy convertors to improve the solar cell efficiency. This work resulted in three scientific publications. Moreover, during this work, he improved his skills on XRD analysis, microscopy (TEM, and SEM with EDX), Thermal Analysis (DSC and TG-DTA), and UV-VIS-NIR Luminescence.
Since beginning of March 2018 he joined FunGlass to conduct fundamental and applied research on phosphate glasses will be prepared by melt quenching. The thermo dynamical and structural properties of these glass species will be studied and also try to correlate with spectroscopic properties for solid state laser applications.
Singarapu Babu received his doctorate degree (Ph.D) in Physics with Solid State Spectroscopy as research area from the SRI VENKATESWARA UNIVERSITY, Tirupati (AP), INDIA, in 2016. The topic of his PhD. thesis was “CERTAIN RARE EARTHS DOPED MULTICOMPONENT FLUORO-PHOSPHATE GLASSES FOR SOLID STATE LIGHTING APPLICATIONS: A PHOTOLUMINESCENCE STUDY”. During his Ph-D work, he prepared, characterized and investigated fluoro-phosphate glasses with superior photoluminescence properties for Solid State Lighting applications. During his Ph-D studies, he improved, his expertise on structural and chemical analysis using XRD, FTIR spectroscopy, Raman spectroscopy, NMR spectroscopy, X-Ray Photoelectron spectroscopy (XPS) Scanning Electron Microscopy (SEM), optical properties using X-Ray Absorption Fine Structure (XAFS) spectroscopy, UV-VIS-NIR absorption and luminescence spectrophotometer interpretation and reporting. He also acquired knowledge on dielectric, electrical, and thermal properties using techniques such as LCR impedance spectrometer, differential scanning calorimeter (DSC), and differential thermal analysis (DTA). The very successful work resulted in contributions to various peer-reviewed International SCI indexed journals and Proceedings.
As of March 2018 he joined FunGlass. His current research interests to conduct fundamental and applied research but not limited to: investigations on luminescent glasses, Coatings on glasses, Oxy-fluoride Glass-Ceramics for Laser (VIS and NIR) and Solar Cell applications by Melt Quenching, Sol-Gel and Spark Plasma Sintering (SPS) methods. A number of techniques will be employed for the characterization of prepared materials.
