Photometer transmission
WebSpectrophotometry is a standard and inexpensive technique to measure light absorption or the amount of chemicals in a solution. It uses a light beam which passes through the sample, and each compound in the solution absorbs or transmits light over a certain wavelength. Spectrometry is measured by a spectrophotometer; an instrument that is … Webphotometer, transmission electron microscopy, UV-visible diffuse reflectance spectrophot-ometer, thermogravimetric analysis (TGA), Raman, Photoluminescence and Brunauer– Emmett–Teller analysis to study the structural, morphological and optical properties.
