Effective photoluminescence in a large-area array of Ta2O5 nanodots (PL of Ta2O5 nanodots)

In this study we present the synthesis of the large-area Ta<inf>2</inf>O<inf>5</inf> nanodot array by utilizing hot filament metal vapor deposition technique. The Ta<inf>2</inf>O<inf>5</inf> 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… CONTINUE READING
