Perovskite quantum dots (QDs) are high-efficiency optoelectronic materials attracting great interest, but further improvement in the luminescence efficiency is crucial for their application. In this work, we enhance both spontaneous emission rate and photoluminescence (PL) intensity of CsPbBr3 QDs by coupling them to a high quality (Q) factor SiO2 microdisk cavity. Compared conventional metal plasmonic cavities, dielectric cavity structure suppresses effects quenching energy transfer, which could introduce complex fluctuations nonradiative decays. As such, obtain 5.9-fold enhancement PL 5.6-fold rate. Moreover, different behaviors phonon sidebands allow us explore components broad peak ensembled QDs. These results demonstrate potential cavities enhancing devices exploring exciton-photophysics perovskite
