(A) The PL and PLE spectra of CLSO:Dy³⁺ and CLSO:Sm³⁺ phosphors. (B) The linear fitting of I_SO/I_S of Dy³⁺ versus C^n/3 in CLSO:0.20Dy³⁺/ySm³⁺ (y = 0–0.32) phosphors. (C) The plotting of η_T versus Sm³⁺ ion concentration. (D) Decay curves of Dy³⁺ in CLSO:0.20Dy³⁺ phosphor excited at 365 nm monitored at 479 nm (I) and 573 nm (II); (III) decay curve of Sm³⁺ in CLSO:0.20Sm³⁺ phosphor excited at 365 nm monitored at 601; decay curves of CLSO:0.20Dy³⁺/0.20Sm³⁺ phosphor excited at 365 nm monitored at 479 nm (IV), 573 nm (V) and 601 nm (VI).
