 5a]. The absorption edge for samples VT400 and VT700 occurred at ~ 503 nm and ~ 470 nm. However, the transmittance reduced marginally with expanding substrate temperature in the NIR spectra selection, which could be attributed to the large particle measurement and deficiency of porosity for VT700. Determine 5b shows the reflectance spe
