Preparation and performance of low-emissivity Al-doped ZnO films for energy-saving glass

Low-emissivity Al-doped ZnO films were deposited on the surface of glass by direct current magnetron sputtering method. The infrared emissivity of sample was focused on. The structural characteristics were investigated by the X-ray diffractometry and scanning electron microscopy, while the properties were measured by a four-point probe, an infrared emissivity measurement instrument and an UV–Vis spectrophotometer. The results show that the...
