dc.description.abstractWe demonstrate coupling of lead halide perovskite nanocrystals to a nanophotonic cavity. From photoluminescence measurements, we observe a factor of 10 enhancement in brightness from the cavity mode emission. We perform room temperature time-resolved lifetime measurements that demonstrate an average spontaneous emission rate enhancement of 2.9 for perovskite nanocrystals within the cavity as compared to those located on the unpatterned surfaces. Our method provides a way towards realizing efficient light emitters and low-threshold lasers, as well as fast nonlinear optical devices, using solution processable materials.en_US
