“…S1, please see the ESI †) are calculated and displayed in Table 1. The s abs of In-1 and In-2 can be obtained from our previous work 28 since UV-VIS-NIR absorption spectra of In-1 and In-2 are measured under the same conditions as In-3. As displayed in Table 1, the values of s abs for In-3 are larger than those of In-1 and In-2, suggesting that there are fewer Er 3+ cluster sites in In-3.…”

“…In recent years, the optical properties of rare earth (RE) 3+ -doped LN single crystals, such as Nd 3+ , Er 3+ , Ho 3+ , Yb 3+ , Pr 3+ , and Dy 3+ :LN, have been studied in detail [1,2,3,4,5,6,7,8,9]; some of these crystals have been widely applied in solid-state optical devices. The trivalent samarium ion (Sm 3+ ), which has a complex energy level structure, exhibits emission in the visible region, and is known for its rich orange emission at 610 nm and red emission 651 nm, both of which originate from the 4 G 5/2 state; such an emission is interesting for many photonic applications.…”

Temperature-dependent and threshold behavior of Sm3+ ions on fluorescence properties of lithium niobate (LiNbO3, LN) single crystals were systematically investigated. The test materials, congruent LiNbO3 single crystals (Sm:LN), with various concentrations of doped Sm3+ ions from 0.2 to 2.0 mol.%, were grown using the Czochralski technique. Absorption spectra were obtained at room temperature, and photoluminescence spectra were measured at various temperatures in the range from 73 K to 423 K. Judd–Ofelt theory was applied to calculate the intensity parameters Ωt (t = 2, 4, 6) for 1.0 mol.% Sm3+-doped LiNbO3, as well as the radiative transition rate, Ar, branching ratio, β, and radiative lifetime, τr, of the fluorescent 4G5/2 level. Under 409 nm laser excitation, the photoluminescence spectra of the visible fluorescence of Sm3+ mainly contains 568, 610, and 651 nm emission spectra, corresponding to the energy level transitions of 4G5/2→6H5/2, 4G5/2→6H7/2, and 4G5/2→6H9/2, respectively. The concentration of Sm3+ ions has great impact on the fluorescence intensity. The luminescence intensity of Sm (1.0 mol.%):LN is about ten times as against Sm (0.2 mol.%):LN at 610 nm. The intensity of the fluorescence spectra were found to be highly depend on temperature, as well as the concentration of Sm3+ ions in LiNbO3 single crystals, as predicted; however, the lifetime changed little with the temperature, indicating that the temperature has little effect on it, in Sm:LN single crystals. Sm:LN single crystals, with orange-red emission spectra, can be used as the active material in new light sources, fluorescent display devices, UV-sensors, and visible lasers.
