dc.description.abstractInfrared-to-visible upconversion luminescence emission in Nd3+-doped 60TeO(2)-10GeO(2)-10K(2)O-10Li(2)O-10Nb(2)O(5) tellurite glasses under cw excitation around 800 nm is investigated. Blue (430, and 475 nm), green (5 0 nm) and yellow-orange (590 nm) energy upconversion emission owing to the P-2(1/2) --> I-4(j) (j=9/2, 11/2, 13/2 and 15/2) transitions of the Nd3+ ions, respectively, was recorded. The dependence of the upconversion intensity upon the excitation wavelength and pump power is also studied. The upconversion excitation mechanism responsible for the observed emission signals is attributed to stepwise multiphoton absorption. (C) 2002 Elsevier B.V. B.V. All rights reserved.
