Glass spherical microcavities containing CdSexS1-x semiconductor quantum do
ts (QDs) are fabricated. The coupling between the optical emission of embed
ded CdSexS1-x QDs and spherical cavity modes is realized. When the luminesc
ence of QDs is excited by a laser beam, the strong whispering gallery mode
resonance with high Q factors is achieved in the photoluminescence spectra.
