LITTLE KNOWN FACTS ABOUT INFRARED OPTICAL.

 5a]. The absorption edge for samples VT400 and VT700 transpired at ~ 503 nm and ~ 470 nm. However, the transmittance lessened a little bit with escalating substrate temperature inside the NIR spectra vary, which might be attributed to the massive particle size and not enough porosity for VT700. Determine 5b shows the reflectance spectr
