Sustainable solid-state method of synthesis, characterisation, and photoluminescence studies of Yb3+/Ho3+ doped YPO4 nanomaterials

Abstract

To encourage the production of [PO4]3- groups, a group of up-converting …down-converting YPO4 Yttrium phosphate compounds were synthesized using the solid-state technique in a basic environment. The noble pureness of the doped matrix was confirmed by the structural studies and Rietveld analysis, whereas growth in the part of the YPO4: Yb, Ho structures was discovered with a higher dopant concentration. The phosphates group, along with the ions Yb3+ and Ho3+, allowed for the UC…DC luminescence. While we observe up-conversion luminescence with colour under the 980 nm continuous movement of wave laser irradiation had been set on the way to the red area, the powerful green emission had been produced by 300 nm excitation. Following the results, materials that are resistant to different applications can use synthetic phosphors.
