Abstract
Ce3+, Sm3+ singly-doped and Ce3+-Sm3+ co-doped sodium yttrium borate Na3Y(BO3)2 phosphors are prepared using a high temperature solid-state reaction route, in order to investigate their spectroscopic properties, luminescence dynamic and energy transfer mechanisms. The weak electron-vibrational interaction (EVI) between Ce3+ ions and their surroundings is demonstrated according to measured spectra and theoretical analysis. The mechanism of the Ce3+ → Sm3+ energy transfer in the host is investigated via luminescence dynamic models. In addition, the potential application of Ce3+-Sm3+ co-doped Na3Y(BO3)2 phosphors in the optical anti-counterfeiting is demonstrated according to the luminescence regulation of excitation wavelength response.
