Abstract
Lutetium oxide nanopowders codoped with Tm3+ and Yb3+ were synthesized by the co-precipitation method. Upconversion luminescence properties of the powder compacts have been investigated upon continuous wave excitation at 980 nm. Blue emission band was observed by naked eye, which was corresponded to the 1G4 → 3H6 transition of Tm3+ ions. However, upconversion spectra revealed that the strongest emission was centered at 809 nm, assigned to the 3H4 → 3H6 transition. Weak red emission centered at 651.5 nm was attributed to the 1G4 → 3F4 transition while considerably weaker ultraviolet emission centered at 361 nm was ascribed to the 1D2 → 3H6transition. The dependence of the intensity of upconversion emissions on the pump power implies two-step and three-step excitation mechanisms of the 3H4 and 1G4 levels, respectively. The possible upconversion schemes are discussed in this paper. Lutetium oxide powders can be sintered into transparent ceramics and high intensity of up-converted IR and blue emissions associated with the 3H4 → 3H6 and 1G4 → 3H6 transitions of Tm3+ in this matrix may offer lasers potential.
