Dynamics and spectral features of exciton emission in strongly quantum-confined metal halide quantum dot systems on two different platforms will be presented. The first involves cooperative photon emission in the form of superradiance in an electronically coupled superlattice, which exhibits polarized superradiance. The second concerns the emission of bright and dark excitons from quantum dots fabricated on a micro-ring cavity, which shows an unequal Purcell effect on bright and dark excitons.
