摘要
采用溶胶-凝胶法在单晶硅Si(100)衬底上制备了ZnO薄膜,研究了退火温度对ZnO结构和光学性能的影响。实验发现,退火可以明显地改善ZnO薄膜的结构和光学性能。随着退火温度的升高,ZnO薄膜的晶粒增大,同时在室温下观察到明显的紫外发光现象,其紫外PL谱峰值变强,并有红移现象。
ZnO films were fabricated by Sol-Gel method on (001) Si substrates. The influence of annealing temperature on structure and optical properties of ZnO films was investigated. Annealing could improve crystallization and optical properties of ZnO films evidently. With the annealing temperature increasing, the grain size became larger and ultraviolet emission was observed at room temperature. While annealing temperature was higher, PL peak was stronger and had a little red shift.
