We present surface-defect passivated Ag-based I-III-VI QDs with PLQYs exceeding 50%. Optical gain is observed in ASE stripe-length experiments. Time-resolved optical spectroscopy reveals long radiative lifetimes, size-dependent inter-valence-band hole relaxation times, and low exciton-exciton annihilation rates.
