To improve the transmittance and enhance the hydrophilicity on the surface of glass, a aluminum-induced method was used to prepare the light trapping structure. The Al thin films were prepared by DC magnetron sputter technique. The effects of annealing treatment at various substrate temperatures on the surface structure, optical properties and wettability of the glass were studied. The glass surface prepared was observed by scanning electron microscopy ( SEM ) . The change of the transmittance of the glass after the process was measured by the UV-VIS spectrophotometer. The wetting property of the bare and etching glass was determined by the contact angle instrument. Results show the different structures of light trapping structure can be prepared by adjusting annealing temperature. The transmittance of the samples annealed at 150℃ reaches 94% within the wavelength range of 480-680 nm. The surface contact angle of the sample annealed at 200℃ decreases to 8. 6°.%为了提高玻璃的透过率,减小其接触角,采用铝诱导方法,用磁控溅射仪在玻璃表面制备铝膜,铝膜经不同温度退火成为铝颗粒,铝颗粒与玻璃反应,脱除氧化铝和残余铝后制得陷光结构.借助SEM、紫外-可见分光光度计、接触角仪等,研究了铝薄膜退火温度对玻璃表面陷光结构、光学性能、润湿性能的影响.结果表明:通过调整铝薄膜的退火温度,制备了不同的陷光结构,150℃退火样品在480~680 nm波长内透过率达到94%,200℃退火样品的表面接触角减小为8.6°.
