Highly
luminescent CsPbBr3 perovskite quantum dots (QDs) are very
attractive for applications
in power-generating devices. The CsPbBr3 QD solution and
its corresponding solid films were satisfactorily prepared. The obtained
QDs were characterized by various techniques such as transmission
electron microscopy, X-ray diffraction, ultraviolet–visible
spectrophotometry, and photoluminescence and radioluminescence spectroscopy.
The performance of the CsPbBr3 QD films as an energy conversion
material in radioluminescent nuclear batteries was analyzed and discussed.
The output performance of different nuclear batteries based on CsPbBr3 QD films was compared and the feasibility and advantages
of using them as radioluminescent layers were investigated. On this
basis, a long-term equivalent service behavior study was conducted
to evaluate the irradiation stability of the CsPbBr3 radioluminescent
layer and predict the service life of this type of nuclear battery.
The distribution state and penetration depth of hydrogen ions in the
films were analyzed and evaluated using physics simulation software.
Optical and electrical characteristics confirmed that this perovskite
material could offer an efficient, stable, and scalable solution for
energy conversion and photoelectric detection in the future.
