Abstract

Zinc-borosilicate glass containing Nd3+ ions has been prepared to study the NIR fluorescence and the violet upconversion emission properties. NIR photoluminescence spectrum has been recorded with the 514-nm line of Ar+ laser and observed three emission transitions of F-4(3/2) —> I-4(13/2,11/2), (9/2). The decay curve of the prominent lasing transition F-4(3/2) —> I-4(11/2) has been measured both at 514-nm line of an Ar+ laser and at 808 nm of a pulsed laser diode. A bright violet color upconversion emission has been measured from a yellow light (I-4(15/2) —> (4)G(5/2) at 576 mn) of a xenon arc lamp. (C) 2002 Elsevier Science B.V. All rights reserved.
