INDICATORS ON IR OPTICAL YOU SHOULD KNOW

 5a]. The absorption edge for samples VT400 and VT700 occurred at ~ 503 nm and ~ 470 nm. Conversely, the transmittance diminished a little with rising substrate temperature while in the NIR spectra array, which may very well be attributed to the big particle dimension and not enough porosity for VT700. Determine 5b shows the reflectance
