Abstract

This paper presents a bulk nanocomposite glass doped with cadmium telluride quantum dots (CdTe QDs) and silver nanoparticles (nAg), exhibiting ultranarrow (FWHM = 13 nm) and ultrafast (90 ps) amplified photoluminescence (PL) at room temperature. Numerical simulations confirm that this enhanced emission results from multiscale light enhancement due to the ensemble of QD-populated plasmonic nanocavities. Power-dependent measurements indicate coherent light amplification exceeding 100 mW. These bulk plasmon–exciton composites offer potential for various applications.
