Lead trihalide perovskite nanocrystals are promising candidates as light sources. Coupling quantum emitters with nanophotonic cavities can significantly boost efficiency, but this approach hasn’t been explored with these nanocrystals. Now, researchers have demonstrated a simple approach for coupling solution-synthesized cesium lead tribromide perovskite nanocrystals to silicon nitride photonic cavities. The resulting room temperature light emission is enhanced by an order of magnitude above what perovskites can emit alone.
