ABSTRACT
This study investigates the effect of growth temperature on the photoluminescence spectra of zinc oxide nanoma-terial synthesized on amorphous glass substrate via the horizontal vapor phase crystal growth method (HVPCG). XRD analysis reveals the hexagonal wurtzite structure of the grown ZnO nanomaterial with growth orientation in the (002) and (101) directions. The room temperature PL spectra of the samples show green emission centered at 510 nm. The strong green emission is caused by antisite oxygen defects in the film.
