Lasing of polymer microspheres doped with AgInS2 quantum dots and plasmonic nanoparticles
Whispering-gallery mode (WGM) microlasers were made of polystyrene microspheres in an aqueous solution of plasmonic nanoparticles and AgInS2 quantum dots. The emission spectra of doped microspheres exhibited narrow peaks corresponding to WGM. The presence of silver and gold nanoparticles reduces the emission intensity and, in the case of gold, simultaneously increases the microlaser quality factor.

Abstract
Whispering-gallery mode (WGM) microlasers were made of polystyrene microspheres in an aqueous solution of plasmonic nanoparticles and AgInS2 quantum dots. The emission spectra of doped microspheres exhibited narrow peaks corresponding to WGM. The presence of silver and gold nanoparticles reduces the emission intensity and, in the case of gold, simultaneously increases the microlaser quality factor.
