Аннотация:Abstract: We demonstrate tunable green lasing from a bromide-based organic-inorganic perovskite
thin-film. The optical feedback required for laser emission is provided by a circular grating
that forms a disk Bragg resonator inside a spin-coated 200 nm thin-film of methylammonium
lead tri-bromide (CH3NH3PbBr3). As the emission spectrum below as well as above the lasing
threshold is reasonably affected by the Bragg grating resonance, it becomes possible to engineerand thus tune the emission between 541 and 552 nm. Our study incorporates the influence of the temperature on both the linear optical properties as well as the emission.
