Abstract

This paper investigates Dy-doped and Dy, Er-co-doped yttrium aluminum garnets (YAG) with the admixture of boron nitride with the aim of using them as efficient thermographic phosphors at high temperatures. The phosphors were synthesized using a conventional high-temperature solid-state method. The influence of two fluxes, BO and LiF/NHF, and the effect of activator and coactivator concentrations were investigated. Additionally, the effect of B and N substituting for Al and O ions, respectively, in the YAG:Dy co-doped with Er was studied for the first time. The changes in the host lattice led to a much stronger photoluminescence compared with the samples without B and N substitution. The admixture of BN also improves the thermal sensitivity of the YAG:Dy and YAG:Dy, Er thermographic phosphors.
