摘要	The up-conversion fluorescence, at low temperature, of Nd3+-doped LaF3 planar waveguides grown on (1 1 1) oriented CaF2 substrates by Molecular Beam Epitaxy is reported. The up-converted emissions excited with a tunable Ti:Sapphire laser are observed in UV-blue, green and orange regions corresponding to the D-4(3/2) --> I-4(J) (J = 9/2, 11/2, and 13/2), (4)G(7/2) --> I-4(9/2) and (2)G(7/2) + (4)G(5/2) --> I-4(9/2) (4)G(7/2) --> I-4(11/2) transitions, respectively. The up-converted emission at 381 nm (D-4(3/2) --> I-4(11/2)), due to a three-photon process, gives rise to the most intense luminescence. The green and orange up-conversion luminescences originate from an energy transfer process involving two Nd3+ ions in the F-4(3/2) excited state while two successive energy cross-relaxations are suggested for the UV-blue emission. The maximum intensity is obtained for Nd3+ content of 1 at% for all the emissions observed. The up-conversion fluorescences are observed for different samples doped in the range 0.5-5 at%.
