THE SMART TRICK OF IR OPTICAL THAT NO ONE IS DISCUSSING

 5a]. The absorption edge for samples VT400 and VT700 occurred at ~ 503 nm and ~ 470 nm. Alternatively, the transmittance reduced a little bit with rising substrate temperature within the NIR spectra vary, which might be attributed to the large particle size and deficiency of porosity for VT700. Determine 5b displays the reflectance spe
