The optical absorption and emission properties of a semiconductor or molecular materials coupled to an optical cavity differ strongly from those of the bare, uncoupled, compounds.[1] For instance, it may intensely absorb light at frequencies for which its intrinsic absorption is very low, or emit light at spectral ranges at which the uncoupled system barely shows luminescence.[2,3] The integration of lead halide perovskites into photonic structures have demonstrated the great potential this approach bears to controllably modify and enhance the photophysical properties of these semiconductors. In this talk, different ways to controllably modify the optical response of lead halide perovskites by tailoring their optical environment will be overviewed. Recent advances in the improvement of the optical quality of perovskite quantum dot solids, which has opened the door to their integration in optical cavities, will be discussed in detail, as well as their implications in the field of photovoltaics, light emitting devices and photodetection.
