SPML · Centre for Interdisciplinary Research (CIDR)
SRM University AP · Amaravati
We synthesise fluorescent carbon materials and shape them into micro-resonators, photonic barcodes, optical gain media and transparent functional films for lighting, sensing and security that can be manufactured without critical or toxic elements.
Sustainable Photonic Materials Lab · SRM University AP
We build optical materials as if the supply chain were part of the design.
Area 01
Photonic microbarcodes & unclonable anti-counterfeit
A physical signature that cannot be printed, copied or cloned.
Area 02
Energy materials & electrocatalysis
Carbon materials for energy storage and catalysis.
Area 03
Sustainable opto-films
Windows that block UV and heat and pass visible light.
Area 04
Metal-free solid-state lasers
A gain medium made from carbon, not from rare earths.
Area 05
Whispering-gallery microbeads & microcavities
Light confined inside a polymer sphere by total internal reflection.

Selected work
Four papers from the current programme, newest first. Keep scrolling and the record arrives one frame at a time, then settles into a quadrant.
All 40 publications →Microbead emitters whose colour is tuned across the visible-to-infrared range, encoding information in multiple spectroscopic levels at once.
10.1002/adom.202503855
Phenyl-modified carbon nitride, a metal-free and rare-earth-free microcavity material, gives whispering-gallery emission with strong fluorescence.
10.1002/adom.202503772
A single metal-free component that emits white light and supports visible-to-NIR whispering-gallery modes from micro-emitters.
10.1039/d6lf00065g
Carbonized polymer dots turned into spectrally adaptable photonic microbarcodes, the encoding vehicle for our anti-counterfeit work.
