Optical interference fringes in CsPbBr 3 perovskite microplate

Abstract While high-reflectivity end faces have been used as resonant cavities to achieve low-threshold lasing in various micro-nano structures of all-inorganic perovskites, the specific influence of the natural surface cavity of a sample on its optical properties has rarely been reported.

Description
Summary:Abstract While high-reflectivity end faces have been used as resonant cavities to achieve low-threshold lasing in various micro-nano structures of all-inorganic perovskites, the specific influence of the natural surface cavity of a sample on its optical properties has rarely been reported. Herein, we systematically investigate the effect of interference effect induced by the surface cavity of wedge-shaped microplates on their optical properties. The competition between interference and re-absorption effects causes oscillation shifts in the fluorescence spectrum and the formation of interference fringes. Variations in the microplate’s thickness have a considerable impact on the interference effect, modifying the sample’s optical properties.
