This work presents a novel white light source. An yttrium aluminum garnet (YAG) phosphor incorporated zinc oxide (ZnO) (ZnO:YAG) film is deposited on a silicon substrate by ultrasonic spray pyrolysis to form a nanostructure diode. A nanoflower consisting of a hexagonal nanopetal is formed on the surfaces of the silicon substrate. A white broad band at the room temperature photoluminescence ranging from 420 to 650 nm for the ZnO:YAG/silicon nanostructure diode was observed. The white broad band consists of the emissions of defect level transition of the ZnO film and the5D4level to the7F6and7F5level transitions of Ce3+ions.

The NO2-sensing properties of the ZnO films prepared by EUSP were investigated. Effect of substrate temperature on the NO2-sensing properties of ZnO films showed that the powder-like ZnO film deposited at 550°C was more sensitive to NO2, and the film illustrated good response-restoration property. Besides, the influence of doping amount on the NO2-sensing properties of the ZnO films at 260°C showed that the ZnO:Al film with the Al content of 0.4mol% presented the best sensitivity, and the ZnO: 3mol % Ag exhibited the highest NO2 sensitivity. The dynamic response tests indicated that the ZnO: Al film was of the highest sensitivity to NO2, and the sensitivity of ZnO: Ag film was lowest.
