Dr. Panthagani Chandar Rao, a distinguished researcher at Kakatiya University, has made remarkable contributions to the field of luminescent materials, nanophosphors, and nanotechnology. With a Ph.D. in Physics, his research focuses primarily on the design, synthesis, and characterization of lanthanide-doped phosphors and advanced optical materials for modern photonic and display applications. Dr. Rao has developed eco-friendly and cost-effective strategies for fabricating Eu²⁺-doped BaMgAl₁₀O₁₇ nanophosphors that exhibit narrow-band blue emission with high luminescence efficiency, contributing to sustainable and high-performance optoelectronic devices. His studies reveal how modifications in synthesis parameters, including low-temperature processes and the use of MCCA additives, influence the structural and photoluminescent properties of nanophosphors, providing insights critical for active display technologies. He has also investigated unusual red-shifts and enhanced photoluminescence under ultraviolet A excitation, highlighting his focus on material optimization for practical applications. Beyond phosphors, Dr. Rao explores nanobiomaterials derived from natural leaves, bridging materials science and green nanotechnology, as well as the broader applications of nanotechnology in luminescent devices. His work extends to thin-film materials, including V₂O₅, where he studies structural, linear, nonlinear, and optical properties using low-cost sol-gel techniques. As an active member of the Luminescence Society of India, the Indian Physics Teachers Association, and the Indian Science Congress, Dr. Rao combines research excellence with academic mentorship, fostering the next generation of scientists. To date, he has authored four high-quality publications, garnering 30 citations, and maintains an h-index of 2 in Scopus, reflecting the growing impact of his research contributions in luminescent nanomaterials and sustainable nanotechnology.
