Abstract:

Ga-doped ZnO nanopowders were obtained from zinc precursor solutions with different Ga concentrations via a simple solvo-thermal route. The optical and electrical properties of the obtained nanopowders have been investigated by XRD, TEM, XPS, PL and Hall effect measurement system (HES). The influence of Ga concentration in zinc precursor solutions on the optical and electrical properties of the product was investigated.

Key words: Ga-doped ZnO; nanopowders; photoluminescence; Hall effect
