Structure and fluorescence characteristics in highly Dy3+ doped tellurite-fluoride glass for white light fiber lasers

Dy3+ and Tb3+ codoped mixed garnet crystals with a high-disorder structure for promising efficient InGaN laser-diode pumped yellow lasers

“…8,13 Among the rare earth (RE) ions investigated for this purpose, Dy 3+ has shown the most promise. [14][15][16][17] When excited at 450 nm wavelength, Dy 3+ undergoes a transition from its ground state 6 H 15/2 to an excited state 4 I 15/2 , resulting in yellow emission through the 4 F 9/2 → 6 H 13/2 transition, as depicted in Fig. 1(b).…”
