Abstract
- CsPbBr3 nanocrystals-glass composite scintillators based on Ce3+-doped borosilicate glass were prepared by melt-quenching method with further heat-treatment. Incorporating Ce3+ into borosilicate glasses matrix, highly enhanced green emission was observed under 365 nm ultraviolet and X-ray excitation. The transmittance of the prepared CsPbBr3 nanocrystals-glass is as high as 80% at 527 nm, fluorescence lifetime is 21.6 ns, and the luminescent quantum efficiency reaches up to 28% after thermal treatment (550 °C, 12 h). Compared with undoped CsPbBr3 nanocrystals-glass, the X-ray excited luminescence intensity of Ce3+ doped CsPbBr3 nanocrystals-glass is around 190%, which indicates that the issue of absorbing ray energy in glass matrix can be effectively solved by incorporation of Ce3+ ions.
