Abstract

Polymorphic ZnO has been prepared by a solution method at low temperature (40–90 °C) and the product has been characterized by transmission electron microscopy, UV–vis absorption, and photoluminescence spectroscopy. It is found that the morphology and microstructure of ZnO can be tuned by varying the growth temperature and crystallization condition. The as-synthesized product exhibits narrowed band gap and strong orange luminescence at 620 nm, which may arise from the interstitial oxygen ion defect introduced into ZnO in the solution growth process.
