Abstract

Blue emission at 486 nm corresponding to the 3P0 ! 3H4 transition in Pr3+:Gd3Ga5O12 (GGG) thin epitaxial film was generated after excitation with infra-red radiation at around 890 nm. The upconversion mechanism was shown to be excited-state absorption from the 1G4 multiplet. The spectroscopic properties of the 1G4 state of Pr3C in GGG were also studied. The emission spectra of Pr3C:GGG bulk crystals and thin film are centred at 1:35 �m, and the measured 1G4 lifetime is about 0:5 �s at room temperature. Blue-wavelength upconversion excitation spectra and direct infra-red excitation spectra allowed us to determine the Stark energy levels in the 1G4 and 1I6 multiplets.
