Electrophoretic deposition (epd) of radioisotope and phosphor composite layer for hybrid radioisotope batteries and radioluminescent surfaces

Abstract

An electrode for beta-photovoltaic cells includes: a substrate formed of a conductive layer with a thickness ranging between about 10 nm to 1 micron; a composite layer of radioluminescent phosphor with radioisotope particles homogeneously dispersed therein formed on conductive substrate with a thickness ranging between about 1 and 25 microns; and a semiconductor comprising a P-i-N/P-u-N junction or a N-i-P-P junction. The radioisotope may be a beta-emitter, such as Ni-63, H-3, Pm-147, or Sr-90/Y-90.
