摘要：

This work reports the optical and morphological modifications in vacuum deposited Gaq3 films upon thermal annealing. The annealing process has been carried out under flowing nitrogen gas for 10 min. It was noticed from the results that at 235 degrees C a broad absorption spectrum and increased photoluminescence to five times stronger than that of pristine film was achieved. Scanning electron microscopy and X-ray diffraction techniques ascertained morphological changes towards the formation of amorphous nanorods. The improvement in optical properties of Gaq3 films was found to be resulted from this morphological modification. The nanostructure formation was seen to be a viable method to enhance the morpho-optical properties of Gaq3 films, making Gaq3 a promising candidate for the application in organic electronics technology.
