Summary Radioluminescent nuclear battery has been widely studied for its miniaturization and long life. In this study, all‐inorganic perovskite quantum dots (CsPbBr 3 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.
