CsPbBr 3 and CsPbBr 1.5 I 1.5 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.

“…[14][15][16] Their high photoluminescence quantum yield (PL QY) and good radiation absorption ability may endow them with high LY. Upon the rst report of RL phenomenon of perovskite nanocrystals (NCs), 17 demonstration of X-ray imaging based on perovskite NCs has been investigated extensively. [18][19][20] Though the emission wavelength of perovskite NCs can be modulated feasibly, their LY is indeed low compared with many commercial scintillators.…”

Fluorescent type nuclear battery (NB) consisting of scintillator and photovoltaic device (PVD) enables semipermanent power source for both small and large devices working under harsh circumstances without instant energy supply. In spite of the progress of device structure design, the development of scintillators with high light yield (LY) and longer emission wavelength catering to PVDs is far behind. Here, a novel Cs3Cu2I5: Mn scintillator, which exhibits an ultrahigh LY of ~ 67000 ph/MeV at an emission wavelength of 564 nm is presented, and this is the highest value at such a long wavelength based on low cost precursors. Besides, doping and intrinsic features endow Cs3Cu2I5: Mn with robust thermal stability and irradiation hardness that 71% or > 90% of the initial radioluminescence (RL) intensity can be maintained in an ultra-broad temperature range of 77 K-433 K or after a total irradiation dose of 38.7 Gy at 333 K, respectively. These superiorities allow the fabrication of an efficient and stable NB, which showed an output improvement of 337% respect to that without scintillator. Luminescence mechanisms including self-trapped exciton, energy transfer, and impact excitation are proposed for the dramatic RL improvement. It is expected that such a new and robust scintillator will open a window for the fields of NBs and radiography.

“…Due to the unique and excellent optical properties of quantum dots, the research on the radioluminescence of quantum dots has been reported successively. [20][21][22][23] In this study, selective perovskite QDs with excellent luminescence properties were used to control the emission spectra of conventional fluorescent materials. The main research method included the characterization of QD fluorescent materials, evaluation of the optical and electrical properties of the RL nuclear battery after spectral regulation and the gain of the electrical properties, and calculation of the adaptation factors for different devices after the spectrum regulation.…”

Summary Radioluminescent nuclear battery has been widely studied for its miniaturization and long life. In this study, all‐inorganic perovskite quantum dots (CsPbBr3 QDs) were selected as a novel wave‐shifting agent combined with liquid scintillator PPO (2,5‐diphenyloxazole). The QDs were used to regulate the emission spectrum to match different GaAs devices. The maximum output power of the RL nuclear battery was greatly enhanced by 1.91 to 2.53 times. Perovskite QDs with adjustable emission spectra were used as wave‐shifting agents and exhibited more excellent properties and application prospects than traditional wave‐shifting agents. The Monte Carlo method was used to simulate the energy deposition of fluorescent materials under various radioactive source models. Results verified the advantages of using liquid radioactive sources and liquid fluorescent materials. The application and reference value of perovskite QDs in nuclear detection and nuclear medical imaging were also discussed.
