Transparent composite films of polymethylmethacrylate with embedded CsPbBr3 colloidal nanocrystals (CsPbBr3-PMMA) were obtained. The optical, photoluminescent, and scintillation properties the studied. CsPbBr3-PMMA had an intense photoluminescence signal a nanosecond-range decay time (2 ns). characteristics different thicknesses studied upon excitation by α-radiation radionuclides 239Pu (Eα = 5.15 MeV) 238Pu 5.46 MeV). sensitivity minimum detectable activity calculated from pulse-height...
in this research, we investigated composites of perovskite nanocrystals with polymer networks to enhance optical properties and stability for further practical applications (e.g. energy harvesting, scintillation detection imaging instruments). These results demonstrate different options improving the luminescence compositions by incorporation cross-linked systems prevention their degradation reduction ambient conditions impact.
The photo- and radioluminescent properties of the CsPbBr3 nanocrystals in PMMA film on BGO LGSO: Pr scintillators are studied. Significant photoluminescence decay has been shown. sensitivity to X-ray alpha-particle excitation demonstrated despite their low loading film.
