Thermal and optical properties of Tm3+: Li6Gd(BO3)3 crystal: A potential candidate for 1.83μm lasers

A comparative spectroscopic study of photoluminescence in Li6GdB3O9:Ce single crystals and crystal-fibers

“…These research works revealed a one-dimensional character of the migration of electronic excitation energy (cationic excitons) along the chains of Re 3 þ ions [5,7]; discovered intrinsic luminescence of LGBO at 3.97 eV, occurring due to radiative transitions in Gd 3 þ ions [4,5]; studied the luminescence properties of trivalent impurity ions in different hosts: Li 6 (Gd, Y)B 3 [38,39], and detected thermoluminescence in LGBO:Eu single crystals [14,40]. Data on luminescence of other impurity ions were presented in rare publications for LGBO (Tm 3 þ [41], Nd 3 þ [3]) and LYBO (Nd 3 þ [8], Er 3 þ [18,30], and Yb 3 þ [19,20,22]). …”

Growth and spectral properties of Tm3+-doped Sr3Y(BO3)3 crystal

“…In the rare earth active ions the Tm 3+ ion can emit the luminescence in the infrared region near 1.5-2.0 m. Since the diode laser-pumped solid-state lasers in 1.5-2.0 m spectra region have many application such as laser radar, medical applications, the Tm 3+ -doped various host materials as a laser active media have been widely studied [23][24][25][26][27][28][29][30][31][32][33][34].…”
