Resumen o descripción
The development of solution-based processes at low temperature and low cost makes zinc oxide attractive as a material for
large area and flexible electronics applications. A process for the deposition of 3D flower-like structures of ZnO on glass
substrates with luminescent properties is presented. The lily flower-like ZnO structures were deposited by a modified
chemical bath deposition method referred to as Successive Ionic Layer Adsorption and Reaction (SILAR). This method is
attractive because allows the control of thickness and composition in the films. Also, the effect of deposition parameters
such as temperature, pH and SILAR cycle’s number in the morphological features were investigated by field emissionscanning
electron microscopy. Two different morphologies, namely lily flower and rice-like structures were obtained with
particle sizes of 0.5-2 μm emitting in a broad band spectrum centered at a wavelength of 530-580 nm when excited with
UV light. ZnO structures deposited at 90 °C, pH: 11.02 showed a lily flower-like shape.
