摘要: Abstract We carry out a comprehensive photoluminescence (PL) study on hydrothermally grown ZnO nanorods to provide insights into the role of hydrogen impurity in materials. Annealing at 1223 K greatly modifies PL properties nanorods, both for excitonic and deep level emissions. The suppression excitons bound H donors as well enhancement emission after annealing suggests removal from lattice. temperature-dependent behavior emissions formation V Zn –H n complexes.
