Embodiment 1
[0041] 1. Preparation work: ultrasonically clean ordinary glass with detergent and deionized water for 20 minutes in turn, and then use concentrated ammonia water (25% by mass) / hydrogen peroxide (30% by mass) / deionized water (volume ratio 1:2) :5) of the mixed solution at 80°C for 30min, and finally ultrasonically cleaned with deionized water for 20min. The treated ordinary glass was dried at 80°C and stored in a clean desiccator for later use. A copper-zinc alloy layer with a thickness of 100 nm was sputtered on an ordinary glass substrate by magnetron sputtering technology, and the film thickness was controlled by film thickness monitoring (FTM). The obtained ordinary glass with a copper-zinc alloy layer was stored in a desiccator for use.
[0042] 2. Reaction steps: The ordinary glass sputtered with a copper-zinc alloy layer with a thickness of 100nm was placed in an airtight container filled with iodine vapor and reacted at 45°C for 8 hours. The resulting product is a ...
Embodiment 2
[0044] 1. Preparation: Same as Example 1, sputtering a copper-zinc alloy layer with a thickness of 100 nm on a common glass substrate.
[0045] 2. Reaction steps: The ordinary glass sputtered with a 100nm copper-zinc alloy layer was placed in an airtight container filled with iodine vapor and reacted at 60°C for 5 hours. The resulting product is a white film. Figure 4 is the SEM photo of the obtained sample, the surface of the film is mainly composed of flaky particles; Figure 5 is the XRD pattern of the obtained sample, and the diffraction peak shown in the figure is Cu 2 ZnI 4 The (112) and (224) crystal planes of (112) and (224) crystal planes show that it has a strong (112) crystal plane dominant orientation.
Embodiment 3
[0047] 1. Preparation: Same as Example 1, sputtering a copper-zinc alloy layer with a thickness of 100 nm on a common glass substrate.
[0048]2. Reaction steps: The ordinary glass sputtered with a 100nm copper-zinc alloy layer was placed in a closed container filled with iodine vapor and reacted at 70°C for 3 hours. The resulting product is a white film. Image 6 It is the SEM photo film of the obtained sample, and the surface is mainly composed of flakes and irregular particles; Figure 7 is the XRD pattern of the obtained sample, and the diffraction peak shown in the figure is Cu 2 ZnI 4 The (112) and (224) crystal planes of (112) and (224) crystal planes show that it has a strong (112) crystal plane dominant orientation.
