(A) Temperature dependent PL spectra of CLSO:0.20Dy3+/0.20Sm3+ phosphor in the range of 303–423 K. (B) The chromaticity diagram of CLSO:0.20Dy3+ (0.286,0.312) and CLSO:0.20Dy3+/0.20Sm3+ (0.309,0.309) phosphors, and digital photograph shows that “FU” and “JIE” are spelled using CLSO:0.20Dy3+ and CLSO:0.20Dy3+/0.20Sm3+ phosphors at 365 nm excitation respectively.
