Abstract

Room-temperature ultraviolet emission of Tm3+ ions at 298 (I61H63), 364 (D21H63), and 391 nm (I61H53) was obtained in Y2O3:Yb3+Tm3+ by continuous-wave diode laser excitation of 980nm. Power dependence analysis demonstrates that five- and six-photon upconversion processes populate the D21 and I61 states, respectively. We believe that the D21 population originates from the cross relaxation G41+F43H43+D21 of the Tm3+ ions, while subsequent energy transfer from Yb3+ to Tm3+ excites the D21 state to the upper I61 state. High multiphoton-induced ultraviolet emission is also expected for other trivalent rare-earth ions similar to Tm3+.
