Organic-inorganic hybrid lead (Pb) perovskites have been recognized as promising light-harvesting materials and attracted tremendous research attention in the photovoltaic field. The power conversion efficiency (PCE) of perovskite solar cells...

Perovskite solar cells (PSCs) show great promises in scalable application owing to the advantages of high conversion efficiency and solution processable fabrication. However, the material cost and device stability greatly...

All-inorganic cesium lead halide perovskite nanocrystals (NCs) have emerged as promising optoelectronic nanomaterials due to their color-tunable and high photoluminescence quantum yield (PLQY). However, poor stability of perovskite NCs in...

InP/ZnSe/ZnS QDs with surface fluorination treatment were fabricated and their nonlinear saturable absorption properties explored. Passive Q-switching of diode-pumped Nd:YVO4 near-infrared laser at 1064 nm (∼1.0 μm) using InP-HF QDs as saturable absorber (SA) is observed.
