Development of a beta radioluminescence nuclear battery

A nuclear battery consisting of a beta source,a phosphor layer and a photovoltaic device was prepared.Planar phosphor layers were synthesized through physical precipitation of ZnS：Cu,ZnS：Ag or SrAlO4：Eu2＋,Dy3＋ phosphors.The radioluminescence（RL） spectra were used to analyze the RL effects of the pho...

Description
Summary:A nuclear battery consisting of a beta source,a phosphor layer and a photovoltaic device was prepared.Planar phosphor layers were synthesized through physical precipitation of ZnS：Cu,ZnS：Ag or SrAlO4：Eu2＋,Dy3＋ phosphors.The radioluminescence（RL） spectra were used to analyze the RL effects of the phosphor layers under beta-particle excitation.Feasibility of using the materials as intermediate absorbers in the beta batteries was studied.The Ⅰ-Ⅴ characteristics of beta RL nuclear batteries with different phosphor layers were tested using 63Ni or 147Pm beta sources.The output power of zinc sulfide matrix phosphor layer was better than that of rare-earth element oxides.In addition,a thin aluminum reflective layer was vacuum-evaporated on the phosphor layers to improve the efficiency of beta RL nuclear batteries,and the results were discussed.
