Micro-ring laser with CH3NH3PbBr3/PEO composite coated inside microcapillary
Micro-ring structures with methylammonium lead bromide (CH3NH3PbBr3)/poly(ethylene oxide) (PEO) composites are fabricated by using a microcapillary as a template. By the fast-drying process, the CH3NH3PbBr3/PEO composite films with a high PEO concentration are deposited to homogeneously cover the in...

| description | Micro-ring structures with methylammonium lead bromide (CH3NH3PbBr3)/poly(ethylene oxide) (PEO) composites are fabricated by using a microcapillary as a template. By the fast-drying process, the CH3NH3PbBr3/PEO composite films with a high PEO concentration are deposited to homogeneously cover the inner surface of the microcapillaries. Under optical pumping, whispering gallery mode lasing is observed from the inner circumference of microcapillaries, which works as a micro-ring cavity. With a reduction in ϕ, the mode number and lasing threshold fluence decrease, suggesting that the stimulated emission is enhanced based on cavity quantum electrodynamics in the CH3NH3PbBr3/PEO composite films uniformly covering the inside of microcavities. |
