Description

<p>Zinc oxide (ZnO) is used as ultraviolet light emitters. ZnO particles are widely used as safety white pigment for baby powder. Thus, ZnO has a potential to use as light emitter for medical field. In this study, stabilized ZnO NPs were prepared in MeOH solution by a precipitation method. The precipitation method is suitable to prepare nano-size particles. However, the surface of the NPs are active, and NPs coagulate each other. Then, they lack the character of NPs. To disturb the coagulation, we add surface treatment agent to the reaction bath. The relationship between the dispersion stability and their preparation conditions were investigated by TEM, the optical absorption and the emission profiles. From the TEM and TED observation, the particle sizes were 10 - 20 nm, and the crystal structure was a wurtzite. UV-vis absorption edge wavelengths of ZnO NPs were observed at around 340 nm.</p>
