CONSIDERATIONS TO KNOW ABOUT INFRARED OPTICAL

 5a]. The absorption edge for samples VT400 and VT700 transpired at ~ 503 nm and ~ 470 nm. Conversely, the transmittance lowered a bit with increasing substrate temperature during the NIR spectra vary, which might be attributed to the big particle measurement and insufficient porosity for VT700. Determine 5b displays the reflectance spe
