Title of Paper:X-ray radioluminescence effect of all-inorganic halide perovskite CsPbBr3 quantum dots

Journal:JOURNAL OF RADIOANALYTICAL AND NUCLEAR CHEMISTRY

Key Words:CsPbBr3 quantum dots Radioluminescence effect Linear response X-ray scintillator

Abstract:CsPbBr3 quantum dots (QDs) were synthesized with toluene and n-hexane as solvent by hot-injection method. Radioluminescence spectra of CsPbBr3 QDs were characterized under different solvents, concentrations, and X-ray irradiation environments. The RL accounted for more than 18.1% of the total fluorescence of CsPbBr3 QDs with toluene (10 mg/ml). The CsPbBr3 QDs with n-hexane only showed RL under X-ray irradiation. Significant linear relationship was found between the RL relative intensity and tube current and solution concentration of CsPbBr3 QDs. Thus, CsPbBr3 QDs is promising scintillator material for X-ray scintillator detection and radioluminescent nuclear batteries.
