Abstract

In the present report, pure zinc oxide and albumen-capped zinc oxide thin films were deposited on a glass substrate by a simple chemical method. The growth rate of the deposited film increases by means of number of dipping linearly. The films deposited were subjected to XRD, SEM, EDX, and UV-visible spectroscopy to analyze the crystal structure, morphology, composition, and optical properties. Structural feature reported that the deposited films were found to be a wurtzite structure. The degree of crystallinity depends on film thickness with deposition time per cycles. The parameters related to film structure, such as stress, strain, dislocation density, lattice constant, and bond length, were determined. The values of the fundamental absorption edge were at 3.28 and 3.06 eV for the deposited films of pure zinc oxide and albumen-capped zinc oxide, respectively. Photoluminescence measurements indicated that the peaks of emission were found to be 375 and 340 nm for zinc oxide and albumen-capped zinc oxide. The effects of an antibacterial activity against different positive and negative bacteria sources were determined.

封盖剂对低成本化学沉积氧化锌薄膜结构、组成、光学性能及抗菌活性的影响

在本报告中，用简单的化学方法在玻璃衬底上沉积了纯氧化锌和蛋白覆盖氧化锌薄膜。随着浸镀次数的增加，沉积膜的生长速率呈线性增加。采用XRD、SEM、EDX、uv -可见光谱等分析了薄膜的晶体结构、形貌、组成和光学性能。结构特征表明，沉积膜为纤锌矿结构。结晶度取决于膜的厚度和每循环沉积的时间。测定了与薄膜结构有关的应力、应变、位错密度、晶格常数和键长等参数。纯氧化锌膜和蛋白包覆氧化锌膜的基谱吸收边分别为3.28 eV和3.06 eV。光致发光测试表明，氧化锌和蛋白包覆氧化锌的发光峰分别为375 nm和340 nm。测定了其对不同阳性和阴性菌源的抑菌活性。
