INDICATORS ON IR OPTICAL YOU SHOULD KNOW

 5a]. The absorption edge for samples VT400 and VT700 occurred at ~ 503 nm and ~ 470 nm. Then again, the transmittance decreased a bit with rising substrate temperature in the NIR spectra assortment, which may very well be attributed to the big particle measurement and lack of porosity for VT700. Figure 5b displays the reflectance spect
