IR OPTICAL CAN BE FUN FOR ANYONE

 5a]. The absorption edge for samples VT400 and VT700 occurred at ~ 503 nm and ~ 470 nm. However, the transmittance diminished marginally with expanding substrate temperature while in the NIR spectra vary, which may very well be attributed to the massive particle sizing and lack of porosity for VT700. Figure 5b shows the reflectance spe
