Photoluminescence (PL), stability, and transmittance of MAPbBr3 QD/AzoPDMS composite film. (a) PL spectra of MAPbBr3 QD/PDMS composite and MAPbBr3 QD/AzoPDMS composite. MAPbBr3 QD/AzoPDMS composite film exhibited λmax at 523.8 nm by absorbing light with a wavelength below 500 nm. (b) XRD analysis of MAPbBr3 QD/AzoPDMS composite film showed that the film is stable for at least a few months. (c) A photograph of transparent MAPbBr3 QD/AzoPDMS composite film. (d) Transmittance spectra of MAPbBr3 QD/PDMS composite and MAPbBr3 QD/AzoPDMS composite which showed transmittance of ~76% and ~53% at 700 nm, respectively.
