Abstract
Absorption and luminescence properties of Nd3+ in B 2O3-Bi2O3 glass system with composition xNd2O3:(70- x)B2O3:30Bi2O 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: 4F3/2 (877 nm), 4F5/2 + 2H9/2 (803 nm), 4S3/2 + 4F7/2 (745 nm), 4F9/2 (684 nm), 2H11/2, (630 nm) 4G5/2 + 2G7/2(583 nm), 2K13/2 + 4G7/2 (526nm) 4G9/2 (519 nm) ← 4I9/2. The emission band at 900 1064 and 1336 nm arising from the transition 4F3/2→4I 9/2, 4F3/2→4I11/2 and 4F3/2→4I13/2 respectively were observed when the sample was excited by lasers working at 750 nm. All intensity are increases with increasing of Nd2O3 concentration. © 2010 Published by Elsevier Ltd.
