Dataset for "Phase Behavior and Substitution Limit of Mixed Cesium-Formamidinium Lead Tri-Iodide Perovskites"

The dataset includes continuous-wave photoluminescence (PL) spectra and PL decay data as a function of temperature for single crystal hybrid perovskite photovoltaic material Cs0.1FA0.9PbI3. PL measurements contain wavelength and intensity for each individual spectra in different temperatures.
