Highly fluorescent phenyl-modified carbon nitride microcavities for rare-earth-free whispering-gallery emission

Our Advanced Optical Materials paper reports phenyl-modified carbon nitride as a rare-earth-free microcavity material with strong fluorescence. It is a step toward sustainable photonic sources that need no critical rare-earth supply chains.

Recruitment

PhD and postdoctoral positions available in the lab

We invite applications to our PhD programme from candidates with an MSc/MS background in Chemistry, Physics or Engineering. NET/GATE-qualified students can join the research group directly, and CSIR-NET fellows receive an additional INR 18,000 per month as a President's Award. Postdoctoral candidates are invited to apply by email. The PhD call is open; the postdoctoral call is closed at the moment.
