“…As one kind of mature fluorescence materials, liquid scintillators are directly sensitive to X‐rays or gamma radiation and can be used to change the spectral wavelength of the rays to the region of visible light 17,18 . Furthermore, liquid scintillators are organic scintillators with high luminous efficiency and are characterized by their low price, adequate attenuation length, long stability (with careful chemical treatment), good plasticity, and inherent radiation resistance 19,20 .…”

Summary The feasibility of utilizing CdSe/ZnS quantum dots (QDs) in liquid scintillator radioluminescent nuclear batteries to improve battery performance was studied. The peak position of the radioluminescence emission spectra of liquid scintillator can be regulated by controlling the QD components. This method is suitable for obtaining a satisfactory spectral matching between fluorescence materials and photovoltaic devices to increase the output performance of the battery. In the experiment, CdSe/ZnS QDs were introduced into Emulsifier‐Safe liquid scintillator, and the output properties of radioluminescent nuclear batteries were investigated via X‐ray. Results indicate that the battery with 15 mg CdSe/ZnS QDs generated the best electric power under different tube voltages. To analyze the X‐ray radioluminescence effects of the liquid scintillator, the radioluminescence spectra of the Emulsifier‐Safe with and without CdSe/ZnS QDs were measured and compared. The spectral matching degree between the Emulsifier‐Safe with different concentrations of CdSe/ZnS QDs and the GaAs device was also analyzed by considering luminescence utilization in batteries. This framework can serve as a guide for the development of a radioluminescent material system for long‐lasting, high‐performance power supplies.
