Sm3+-Doped Y2Ge2O7 Orange-Red Phosphor Prepared via the Sol–Gel Method for Multimodal Applications: A Study of of the Effect of Dopant Concentration on Structural and Optical Properties

This work reports, for the first time, the synthesis of single-phase trivalent samarium-doped yttrium pyrogermanate (Y2Ge2O7:xSm3+) phosphors via the sol–gel method. The crystalline structure, photoluminescence mechanisms, energy transfer dynamics, and optical thermometry properties were systematically investigated. Th...
