In this study, LaF₃–LaOF:Yb³⁺/Ho³⁺ upconversion (UC) phosphors were synthesized via a solid-state reaction and their optical properties were analyzed. The analysis of photoluminescence (PL) characteristics revealed strong emission at a wavelength of 543 nm for molar ratios of La:Yb:Ho = 1:x:y, where x = 0.04–−0.06 and y = 0.01–−0.03. The pump power dependence of phosphor PL and the fluorescence lifetime were then measured, and the mechanism of UC PL is discussed.
