摘要: Abstract The present work reports on the tunable optical emission from oxygen vacancies in ZnO nanorods. common green luminescence at room temperature originated vacancy defects can be mediated by simply controlling pH values of alkaline solutions without introduction any intentional dopants. peak energies band are found to monotonously tuned range 2.17 2.47 eV, which could promote applications wavelength optoelectronic devices. dependent behavior exciton transitions and recombinations nanorods is investigated detail. It suggested that localized bound (LBX) attached near lateral facets survive up nearly due large binding energy.
