Abstract

Room-temperature ultraviolet emission of Tm³⁺ ions at 298 (Formula presented), 364 (Formula presented), and 391 nm (Formula presented) was obtained in Y₂O₃:Yb³⁺-Tm³⁺ by continuous-wave diode laser excitation of 980 nm. Power dependence analysis demonstrates that five- and six-photon upconversion processes populate the ¹D₂ and ¹I₆ states, respectively. We believe that the ¹D₂ population originates from the cross relaxation (Formula presented) of the Tm³⁺ ions, while subsequent energy transfer from Yb³⁺ to Tm³⁺ excites the ¹D₂ state to the upper ¹I₆ state. High multiphoton-induced ultraviolet emission is also expected for other trivalent rareearth ions similar to Tm³⁺.
