Structure and optical properties of Lu2SiO5:Ce phosphor thin films Academic Article uri icon

abstract

  • Luminescent, cerium doped Lu2SiO5 thin films with C2c symmetry have been prepared by pulsed laser deposition (PLD) at temperatures much lower than the crystallization temperature (2150C) of the corresponding bulk crystals. The PLD grown films show the typical luminescence resulting from the Ce3+5d-4f transition. Maximum luminescence efficiency was observed for films prepared at an oxygen partial pressure of 200mTorr at 600C. These conditions reflect a balance between Ce4+Ce3+ interconversion and the crystalline quality of the films. The results indicate that PLD offers a low temperature deposition technique for complex oxide phosphor materials.
