Field emission scanning electron microscopy image of the as-prepared sample.

FIG. 2.

PL spectra of the as-prepared sample. (a) PL spectra at different temperatures (all spectra are normalized by the UV peak intensity and shifted in the vertical direction for clarity). (b) Typical Gaussian-fitting analysis of the PL spectrum at (correlation coefficients: 0.99).

FIG. 3.

(a) Gaussian-fitting violet emission bands at different temperatures. (The curves from top to bottom correspond to the temperatures shown in the left, respectively.) (b) The temperature-dependent peak position for the three emission bands. (Dash-line: aid to eyes; Solid line: fitting result by Varshni formula).

(a) Schematic illustration of the band structure and the proposed UV, violet, and green emission processes, NR: Nonradiative transition. (b) Model of the localized electrons at defect levels and their transition process with increasing temperature. (c) Model of the green emission with increasing temperature.
