| 摘 要： | 通过向溶胶前躯体溶液中加入与金属阳离子不同比例的柠檬酸,用溶胶凝胶旋涂方法制备透明并且致密的Dy3+掺杂的LaVO4薄膜.当柠檬酸与金属阳离子的比例为2∶1时,制成的薄膜对可见和红外光的透过率达到90%左右,以波长为310 nm的光激发薄膜时可以得到对应于4F9/2-6H15/2和4F9/2-6H13/2跃迁的波长为484 nm(蓝光)和576 nm(黄光)的发射波,讨论Dy3+掺杂的LaVO4薄膜在染料敏化太阳能电池里的潜在应用.

| Abstract: | Transparent and compact LaVO4:Dy3+ thin films were prepared by a spin-coating method with different ratios of citric acid to metal ions in the precursor solution.The transmittance of LaVO4:Dy3+ thin films reached around 90% in the visible and infrared region with the optimum ratio 2∶1 of citric acid to metal cation.The LaVO4:Dy3+ films were excited by the 310 nm ultraviolet light and emitted the characteristic emissions of Dy3+ peaking at 484 nm(blue) and 576 nm(yellow) due to the transitions of 4F9/2-6H15/2 and 4F9/2-6H13/2,respectively.The potential application of LaVO4:Dy3+ film in the dye-sensitized solar cell(DSSC) was also discussed. |
