The characteristics of upconversion luminescence of CaF2:Er crystalline powders were investigated upon excitation of Er3+ ions to the 4I13/2 level by laser radiation at 1531.8 nm. The energy yield values of upconversion luminescence were determined for the spectral ranges 380–780 and 380–1100 nm. It was found that upconversion luminescence of CaF2:Er powders with concentrations of 0.5, 2, 4, 6, 8, 10, 11, 13, 15, and 17% of Er3+ ions is characterized by correlated color temperatures of about 5100, 2142, 1726, 1738, 1773, 1757, 1762, 1765, 1735, and 1714 K, respectively.
