Abstract

Abstract: NaGdF4:Eu3+/AAO thin films were prepared on porous anodic aluminum oxide (AAO) template surface via a hydrothermal process and the effects of some processing variables such as preparing method, the amount of NaGdF4:Eu3+, annealing temperature, were investigated. The crystal structure, morphology and luminescent properties of the as-prepared NaGdF4:Eu3+/AAO thin films were characterized by X–ray powder diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence (PL) spectra. XRD results show that the phase transition of NaGdF4:Eu3+/AAO thin films from the hexagonal phase to the cubic phase occurs at about 500℃ in air. SEM images indicate that the preparing method influences obviously the morphology of NaGdF4:Eu3+/AAO thin films, NaGdF4:Eu3+/AAO thin films with the rectangle morphology were prepared by a two-step hydrothermal process, and however the one-step hydrothermal process was employed to prepare NaGdF4:Eu3+/AAO thin films without any special morphology. The amount of NaGdF4:Eu3+ in the solution and the annealing temperature do not obviously affect the morphology of NaGdF4:Eu3+/AAO thin films. PL results show that the characteristic emission of NaGdF4:Eu3+/AAO thin films with hexagonal or cubic NaGdF4 structure is Eu3+ 5D0→7F2 transition.

Key words: NaGdF4:Eu3+, Thin film, AAO template, Phase transition, Luminescence
