Abstract

Summary: CsPbBr3 and CsPbBr1.5 I1.5 perovskite quantum dots (QDs) are synthesized by hot‐injection with PPO (2, 5‐diphenyloxazole) as a fluorescent material for radioluminescent nuclear battery. The results reveal that the fluorescence of the QD/PPO system consists of radioluminescence (4.79%‐5.35%) and photoluminescence (nearly 95%). The addition of QDs leads to more excellent optical and electrical properties of radioluminescent nuclear battery. The peak position of the radioluminescence spectra of QD/PPO can be regulated by controlling the components of QDs. This strategy is suitable for obtaining a satisfactory spectral matching factor for different photovoltaic devices to obtain outstanding output performance. Moreover, good selection of QD/PPO as a fluorescent material can significantly improve the overall output performance of the radioluminescent nuclear battery. The linear relationship between optical and electrical properties was presented. Perovskite QDs exhibit excellent application prospects for the (α, β, γ, and X‐ray sources) radioluminescent nuclear battery and X‐ray imaging technology. Abstract : A quantum dot (QD)/2, 5‐diphenyloxazole radioluminescent nuclear battery was developed; its luminescence mechanism was studied. The significant improvement in the optical and electrical properties of the radioluminescent nuclear battery mainly due to QDs regulates the RL spectra. Perovskite QDs also has excellent application prospects for the (α, β, γ, and X‐ray sources) radioluminescent nuclear battery and X‐ray imaging technology. This paper presents the results and laws of scientific, which is inside the scope of International Journal of Energy Research .
