摘要：
Yb3+-Tm3+ codoped KLnF(4) (Ln = Y, Yb and Gd) phosphors have been synthesized by a solid-state reaction technique. The results revealed that KYF4 and KYbF4 phosphors crystallize in hexagonal structure and KGdF4 phosphor form in mixed phases. Prepared phosphors are subjected to photoluminescence studies under 980 nm and 356 nm wavelength excitation. The emission colour is examined using the CIE chromaticity diagram for the different host matrices. The results show that the developed phosphors could be useful in the field of lighting and emission colour tuning based applications. (C) 2019 Elsevier Ltd. All rights reserved.
