Abstract

Uniform and hexagonal ZnO micro rods are successfully prepared by low temperature aqueous chemical growth method. Concentration ratios of ZnAc and HMTA precursors affect the sizes of the micro rods at a given temperature and time. The ZnO micro rods exhibit intense UV emissions and fast lifetimes of 30 to 40 ps. The sample having highest surface to volume ratio exhibits the most intense UV emission. With the ease on the isolation and manipulation of these structures, these UV emitting ZnO micro rods have potential use for future optoelectronic applications.
