Unlocking triple-band persistent luminescence: invisible UVC–UVB and visible red emission through structural modulation of Na 2 SrSi 2 O 6 :Pr 3+ cyclosilicate

Year: 2025

Type: article

Abstract: increases, the phosphor exhibits a spectral transition from UVC to UVB within the ultraviolet region. Notably, the applications of this phosphor were assessed in bright-field and dark-field imaging, showcasing its considerable potential for high-contrast monitoring in bright daylight, and advanced optical marking technologies. This work advances the development of visible-to-invisible persistent luminescent materials and offers a good example of engineering the cyclosilicate matrices for luminescence spectrum tuning.
