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

X-ray radioluminescence effect of all-inorganic halide perovskite CsPbBr3 quantum dots 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Radioanalytical and Nuclear Chemistry Springer Journals

Abstract

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.
