Abstract

Zn_0.3Al_0.25Pb_0.3Li_0.098Yb _0.1Tm_0.002F_2.354 amorphous fluoride particles were prepared by pulsed laser ablation. Under a 978-nm laser diode excitation, intense ultraviolet and blue upconversion emissions were observed in the particles. Intensity dependence of the upconversion emissions on the pump power was measured. The results show that the population of the states ¹I₆, ¹D₂ and ¹G ⁴ may come from a five-photon, four-photon and three-photon energy transfer upconversion process. In addition, ultraviolet (¹I ₆ → ³F₄ transition) and blue ( ¹D₂ → ³F₄ transition) upconversion stimulated emissions were observed in the particles.
