Preparation and Photoluminescence Properties of Quantum Size Zinc Oxide Colloids

Abstract:

Article Preview

Quantum size ZnO colloids were prepared by sol-gel method and size of colloids together with the luminescence properties were changed by varying preparing time and temperature. The absorption onset and the maximum of fluorescence peak of the ZnO colloid have obvious shift in UV region and visible light region respectively. The relationship between luminescence properties and energy level splitting is discussed in detail based on the experimental results.
