Preferential Crystallographic Orientation and Optical Properties in (Ag,Zn)-Based Oxide Nanoparticle Thin Film Depending on Spark Voltage
The effect of spark voltage on nanoparticle (NP) formation, crystal structure, and optical properties of Zn and Ag-containing metal oxides produced using the spark-discharge (SD) technique was investigated.Quasispherical-shaped nanocrystals were observed in ZnO, Ag:ZnO, and AgO NP samples prepared at different spark voltages.The NP sizes in ZnO and
