Advanced Ultraviolet Persistent Phosphor for Enhanced Optical Storage in Bright Conditions

Researchers have investigated the crystal structure and photoluminescence properties of the ScBO3:Bi3+ phosphor, revealing its potential for optical information storage and ultraviolet light emission. The study, utilizing X-ray diffraction and spectroscopic techniques, established that ScBO3:Bi3+ exhibits excellent structural integrity and uniform element distribution. Notably, the material displays a highly narrow ultraviolet emission peak at 299 nm, underpinned by efficient excited state transitions of the Bi3+ ion. The photoluminescent and thermoluminescent behaviors were enhanced under white light and thermal stimulation, revealing the material’s capacity to store and release energy, with optimal performance noted at specific illuminance levels. Additionally, dynamic experiments demonstrated the phosphor’s ability to encode and decode binary information through X-ray exposure and light stimuli. Enhanced stability and moisture resistance position ScBO3:Bi3+ as a promising candidate for advanced optical storage applications.
