Luminescence of Nd3+- Doped Bi2O3-B2O3 Glass System

Absorption and luminescence properties of Nd3+ in B2O3-Bi2O3 glass system with composition xNd(2)O(3):(70-x)B2O3:30Bi(2)O(3) are measured for the composition range 0 <= x <= 2.5 (in mol%). The glasses were prepared by normal melt-quench technique and investigated their optical and photoluminescence properties. From uv-visble spectrophotometer data, the various spectroscopic transitions observed are as follows: F-4(3/2) (877 nm), F-4(5/2) + H-2(9/2)(803 nm), S-4(3/2) + F-4(7/2) (745 nm), F-4(9/2) (684 nm), H-2(11/2), (630 nm) (4)G(5/2) + (2)G(7/2)(583 nm), K-2(13/2) + (4)G(7/2) (526nm) (4)G(9/2) (519 nm) <- I-4(9/2). The emission band at 900 1064 and 1336 nm arising from the transition F-4(3/2) -> I-4(9/2), F-4(3/2) -> I-4(11/2) and F-4(3/2) -> I-4(13/2) respectively were observed when the sample was excited by lasers working at 750 nm. All intensity are increases with increasing of Nd2O3 concentration. (C) 2012 Published by Elsevier Ltd.
