Abstract
The design, fabrication, and testing of beta radioluminescence (RL) nuclear battery based on the ZnS:Cu phosphor layers with plane and V groove structures are presented. The RL spectra and current–voltage characteristic curves were used to investigate the optical and electrical properties with 63Ni and 147Pm. For different structures, their emission peaks are all at 530 nm. The Monte Carlo simulation code was employed to analyze the device performance. The V groove structure has the ability to provide improved for an appropriate radiation source. Overall, a suitable phosphor layer structure can provide a new route to exhibit higher energy conversion efficiency.
