| सारांश: | Заглавие с экрана Fluorescent materials are widely used for anti-counterfeiting of information security and commodities. However, the increasing requirements for fluorescent anti-counterfeiting technology urgently require the development of novel fluorescent materials with multicolor fluorescence, single component, and excellent stability. Herein, a new color tunable Ba0.94Ca0.06ScO2F: Eu2+, Bi3+, K+ perovskite phosphor with dependence of excitation wavelength for high-level anti-counterfeiting is reported. The fluorescence spectra of Ba0.94Ca0.06ScO2F: Eu2+, Bi3+, K+ perovskite show the tunable emission band with the peak between 479 and 509 nm. It is worth noting that the peak intensity ratio at 479 and 509 nm changes with the dependence of the excitation wavelength Текстовый файл |
