中文摘要：
对以热蒸发法制备的超薄Ag薄膜,扫描电子显微镜结果显示其呈纳米尺度的颗粒状,由透射谱测量发现其具有表面等离子体激元特征.检测到不同条件制备纳米Ag薄膜的表面等离子体共振吸收峰的位移规律,且纳米Ag材料具有选择性的透过、反射特性.通过不同的制备条件,得到了在长波范围内透过率超过90%、在表面等离子体共振峰值位置处反射率接近50%且峰位可调的光学薄膜材料.这种薄膜材料有望成为应用在薄膜太阳电池中间层中具有潜在性光管理功能的光学薄膜材料.
英文摘要：
Silver nano-films were prepared by thermal evaporation.Scanning electron microscope observations showed that the silver films have nano-structures in morphology.The optical properties of silver nano-structures were obtained by ultraviolet-visible spectrometry,which shows the resonance wavelength of surface plasmon.Precise control of thermal deposition parameters allows the fabrication of silver films on glass substrates with tunable surface plasmon resonance wavelength,which makes the films to have tunable optical properties of transmittance and reflection.In this work,we have prepared silver nano-films with over 90% transmittance in the near-IR region and near 50% reflection in the visible region near the surface plasmon resonance wavelength.Due to the novel optical properties,silver nano-films have an enormous light management potential for use as an interlayer in thin-film solar cells.
