Abstract
We have observed ultraviolet upconversion fluorescence from the D-4(3/ 2) and P-2(3/2) levels of Nd3+ in fluoroindate glass under infrared pu mping. It was found that the excitation of a large population in the F -4(3/2) metastable level allows to achieve strong upconversion emissio ns at 354 and 382 nm. A simple rate equation model reproduces the temp oral behavior of the upconverted emission and allows us to estimate th e energy transfer rate among three Nd3+ ions participating in the proc ess.
