Abstract

Abstract Pr3+ – Yb3+ co-doped LaNbO4 phosphors were obtained by solid-state reaction and their upconversion properties were investigated. XRD analysis demonstrated the absence of secondary phase in the as-prepared materials. UC measurements revealed RGB and IR bands whose intensities have been improved by the increment of Yb3+ concentration. In addition, the phosphors showed a deep red emission at 652 nm (3P0 → 3F2) which is strongly related to the local asymmetry of Pr3+ sites according to the Judd–Ofelt's theory. The CIE color coordinates shift from the green region to the blue region suggesting the phosphors can be tuned by adjusting the concentration of Yb3+. Furthermore, the chromatic coordinates of the LNO: Pr0.1% - Yb2% phosphor did not show significant variation at different pump powers indicating this material could be employed in non-tunable display devices and security applications.
