Two-photon pumped amplified spontaneous emission based on all-inorganic perovskite nanocrystals embedded with gold nanorods
Source abstract
Abstract
Abstract CsPbBr3 nanocrystals have attracted great interest owing to their high fluorescence quantum efficiency, adjustable photoluminescence wavelength, and good stability. We report a device that consists of disordered gold nanorods underneath a film of CsPbBr3 nanocrystals. Two-photon pumping using femtosecond laser pulses at 800 nm enables amplified spontaneous emission (ASE) at about 523 nm. In this work, a narrow peak with linewidth of 5 nm is observed when the pump fluence reaches a low threshold of 0.65 mJ/cm2. The results show that plasmonic resonance of gold nanorods improves the emission transition rate and enables low threshold ASE.
