Abstract

SiO 2 nanostructures have been fabricated by sequential etching/passivation treatment of an amorphous SiO 2 layer, using mixture of SF 6, H 2 and O 2 gases. Photoluminescence measurements depicts that nano-textured SiO 2 films have emission spectra between 530 and 580 nm depending on the details of the sample treatment. The effects of sequence numbers, post-RIE-process hydrogenation treatment, and annealing temperature on the PL characteristics were explored. It is observed that annealing the porous SiO 2 nanostructures significantly increases the PL intensity. Increasing either the plasma current or hydrogenation time will cause a redshift in the PL spectrum. The morphology of the SiO 2 nanostructures has also been studied using field-emission scanning electron microscopy.
