Abstract
- In this study we present the synthesis of the large-area Ta 2 O 5 nanodot array by utilizing hot filament metal vapor deposition technique. The Ta 2 O 5 nanodots were arranged in a large-area array on a Si wafer, and their average diameter is ∼ 35 nm. X-ray photoemission spectroscopy (XPS) revealed the stoichiometric Ta and O compositions of Ta 2 O 5 nanodots. Raman spectroscopy showed the Ta 2 O 5 nanodots to be of orthorhombic (β) crystal. Photoluminescence (PL) spectroscopy displayed that the β-Ta 2 O 5 nanodots provided green and red light emissions at room temperature.
