Published: April 16, 2025

Abstract L‐Ta 2 O 5 :Er 3+ /Yb upconversion phosphors were synthesized by employing the molten salts method with B 3 as solvent. The optimal doping concentrations of Er and Yb are 0.2 2.5 mol%, respectively. green luminescence (UCL) integral intensity acid‐pickling sample reached 40% β‐NaYF 4 under 980 nm laser excitation. may take sites Ta 5+ insert into interlayers . Using ratio (LIR) technique, relative temperature sensitivity was obtained to be 0.95 %K −1 at 303 K. outstanding pure UCL high‐temperature can applied display sensing.
