退火温度对GdBO3∶Eu3+/AAO薄膜形貌和发光性质的影响
Influence of The Annealing Temperature on The Morphologies and Luminescent Properties of GdBO3∶ Eu3+/AAO Thin Films
摘要
Abstract
GdBO3: Eu3+ thin films were successfully prepared on porous anodic aluminum oxide ( AAO) template surface with a pore size of 100 nm by using a hydrothermal process combined with high-temperature annealing. The morphology, crystal structure, and luminescent properties of the as-prepared GdBO3: Eu3+ /AAO thin films were characterized. The morphologies of the as-prepared GdBO3: Eu3+ /VAAO thin films could be controlled through adjusting the annealing temperature. X-ray diffraction (XRD) and photoluminescence (PL) results show the as-prepared GdBO3: Eu3+ materials are vaterite-type GdBO3 phase. PL results indicate the relative intensities in 5D0→7F2 and 5D0→7F1 transitions are very sensitive to the annealing temperature, the ratio value of the red emission (5D0→7F2) to the orange emission (5D0→7F1) of GdBO3: Eu3+ /AAO samples increase with the decrease of the annealing temperature. The color purity improvement of GdBO3: Eu3+/AAO thin films is obtained by decreasing the annealing temperature.关键词
