Abstract
Spectroscopic properties of NdSUP3+SUP-doped barium phosphate glasses for Laser application
Highlights
In recent years rare earth ions (RE3+) doped glasses have been investigated because of their potential applications in the field of laser technology and optical communication systems [1,2]
The present paper explores the preparation of barium phosphate glasses doped with different concentration of Nd3+ ions and their characterization using optical absorption and near infrared (NIR) emission in order to test the suitability for laser applications in NIR region
The absorption peaks centered at around 356 nm, 429 nm, 476 nm, 512 nm, 524 nm, 582 nm, 627 nm, 678 nm, 745 nm, 802 nm and 871 nm are assigned to transitions from ground state 4I9/2 to the higher excited states 4D3/2+4D5/2, 2P1/2, 4G11/2 + 2D3/2 + 2G9/2 + 2K15/2, 4G9/2, 4G7/2, 4G5/2 + 2G7/2, 2H11/2, 4F9/2, 4F7/2 + 4S3/2, 4F5/2+2H9/2 and 4F3/2 respectively in 4f3 electronic configuration of Nd3+ ion
Summary
In recent years rare earth ions (RE3+) doped glasses have been investigated because of their potential applications in the field of laser technology and optical communication systems [1,2]. Phosphate glasses are very interesting materials due to physical properties. These glasses are regarded as better hosts for RE3+ ions due to high transparency, low melting temperature, high thermal stability and low viscosity [5, 6], which render them useful for a wide range of real-world applications. BaO can improve thermal properties of phosphate glasses [9]
