摘要
The europium-doped barium strontium titanate (BST:Eu) films find application in ferroelectric as well as in optoelectronic devices. In this paper, we report the pulsed laser deposition (PLD) of BST:Eu thin films. The structural and optical properties of the PLD-grown BST film have been investigated and correlated. The photoluminescence spectra show the prominent transitions of Eu3+ ions at 550 nm (D-5(1)-F-7(2)), 615 nm (D-5(0)-F-7(2)), and 669 nm (D-5(0)-F-7(3)) upon excitation with 408 nm. The luminescent properties of BST:Eu thin films follow a close correlation with the crystallinity of the thin films. Films deposited at a lower substrate temperature show good luminescent characteristics. (C) 2010 The Electrochemical Society. [DOI: 10.1149/1.3432564] All rights reserved.
