“…Also, the EQE of the GaAs device was reported 19% -74% at a wavelength range of 375 -450 nm [22] . So the GaAs solar cell device is convenient for absorption of the Cherenkov light, but the more efficient device is the triple-junction solar cell which used for output power investigation.…”

It is interesting to note in recent years for a large number of researchers the topic of photonic crystals (PhCs) because of their new and useful properties. In addition, there are many advantages to photonic crystals materials as a high reflectance materials as well as the high transmittance materials based on the target application. The calculations were done for Aluminum oxide and titanium oxide (Al2O3/TiO2) composite photonic crystal in one dimension, which shows a high reflectivity (~ 99 %). The chosen photonic crystal composite can be useful to reflect the Cherenkov light many times which comes out from Cherenkov radiation by using radioisotope 90Sr-90Y. The output intensified light has power 1.45 µwatt and 1.45 nwatt for 90Sr-90Y with the activity 1Ci and 1mCi respectively, that can be used for micro/nano-power source applications.

Summary This work investigated the preparation and optimization of phosphor layer for radioluminescent nuclear battery, and analyzed the property change of the phosphor after irradiation. ZnS:(Cu, Al) with grain size of 5 μm was selected as the phosphor material, and AlGaInP semiconductor was used as the photovoltaic unit. Monte Carlo modeling was used to simulate energy deposition, absorbed dose, penetration of β particles in the phosphor. The optimized coupling scheme of radioisotope sources and phosphor layer was obtained based on comparison particle penetration depth and the output power of radioluminescent nuclear battery. The phosphor layer with 60Co γ‐radiation enhanced the luminescence property up to 50% at the radiation dose of 871 kGy, which is considered as an optimized method of phosphor layer preparation. The radiation of 10 MeV electron was conducted to study the degradation based on the microscopic lattice characteristics, morphological changes, optical and electrical properties. Phosphors have excellent radiation resistance. The output power of nuclear batteries has only declined by 43% even when electron radiation dose reaches 8.56 MGy. The prospect for utilizing ZnS:(Cu, Al) phosphor as radiant energy conversion materials in nuclear battery was also discussed. Results provided an effective guideline for predict the service conditions of radioluminescent nuclear battery.

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.
