Abstract

Ultraviolet upconversion emissions from high energy levels (5D1, 5L8, 5L9,5G5, and 5L10) of Tb3+ were observed in the NaYF4:Tb3+, Yb3+ microcrystals under excitation of a 976 nm laser diode at room temperature. These energy levels were populated by energy transfer and excited state absorption processes. Power dependence measurements confirmed it was caused by a three-photon upconversion process. Concentration quenching did not strongly affect the population of these levels.
