Substrate and Excitation Intensity Dependence of Saturable Absorption in Perovskite Quantum Dot Films
Saturable absorption in perovskite quantum dot (PQD) films, leading to saturation in photoluminescence (PL), is reported. PL of drop-casting films was used to probe how excitation intensity and host–substrate influence the growth of PL intensity. The PQD films were deposited on single-crystal GaAs,...
