The Eu3+/Sm3+-co-doped CaWO4 and CaMoO4 scheelite-type phosphors were successfully synthesized by high-temperature solid-phase method investigated in detail for their promising applications luminescence thermometry. Scanning electron microscopy (SEM) X-ray diffraction (XRD) analyses used to study the structure morphology of synthesized. co-doped CaMO4 (M = W, Mo): Eu3+/Sm3+ showed characteristic emission peaks at 534, 594, 657 705 nm corresponding intra-configurational transitions 5D1→7F1, 5D0→7F2, 5D0→7F3 5D0→7F4 Eu3+ ions, as well other emissions 564, 603 648 nm, which ascribed 4G5/2 → 6H5/2, 6H7/2, 6G9/2 Sm3+, respectively. temperature sensing properties both based on different evolution several bands Sm3+. Specifically, using intensity ratio (LIR) technique, we found that monitoring LIR parameter 652/617 CaMoO4:1%Eu3+/1%Sm3+ maximum relative sensitivity 1.28% K-1 can be achieved cryogenic T-range (93 K). Whereas, utilizing same CaWO4:1%Eu3+/1%Sm3+ results slightly smaller 1.18% K-1. obtained results, indicate developed may work effective, remote sensors, having great application potential optical
