CsPbBr3 Quantum Dot Films with High Luminescence Efficiency and Irradiation Stability for Radioluminescent Nuclear Battery Application

“…A radioluminescent nuclear battery, which is an extensively researched important branch of batteries nowadays, consists of three main components, namely, radiation sources, radioluminescent materials, and photovoltaic devices. − The usual conversion approach converts the radioisotope energy into photons via a phosphor and then converts these photons to electricity via a semiconductor junction device. Although the additional radioluminescence (RL) step may lead to a decrease in energy conversion efficiency, this approach can also protect the irradiation-sensitive semiconductors from lattice damage. − In order to improve the electrical properties of the radioluminescent nuclear batteries, the specification parameters and structural optimization of these three components have been extensively explored and summarized. − Numerous corresponding studies have also been carried out, such as using diverse energy conversion materials, optimizing the structure design, adopting a mixture of radioactive sources and phosphor layers, and adjusting the physical parameters. − …”

Mn2+ Induced Significant Improvement and Robust Stability of Radioluminescence in Cs3Cu2I5 for High Performance Nuclear Battery

“…In the past decade, investigations on the design of the device structure , [4][5][6] application of various scintillators (organic or inorganic ones), 7 effect and optimization of physical parameters, [8][9][10] and coupling between scintillators and PVDs have been carried out to improve the NB e ciency. 11 Despite the power output and e ciency of NBs have been improved signi cantly, the scintillators employed in these researches were mainly conventional transition or rare earth metal doped phosphors, 7,12,13 which typically possess short emission wavelength or low light yield (LY).…”
