Abstract

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. Abstract : A technique that uses liquid scintillator and quantum dots coordinated regulation technology to optimize the performance of radioluminescent nuclear battery is proposed. Liquid scintillation converts radiant energy into light energy, and quantum dots adjust emission wavelength on this basis. This synergistic regulation and enhancement effect of nanomaterials can effectively improve the output performance of optoelectronic devices. Such nanomaterials provide a new idea for the development of energy conversion technologies and open up endless possibilities for their application.
