INDICATORS ON INFRARED 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 increasing substrate temperature within the NIR spectra vary, which could possibly be attributed to the big particle size and insufficient porosity for VT700. Determine 5b shows the reflectance
