Witryna11 lip 2007 · FTIR spectra. Figure 1 compares the FTIR spectra of solid crystalline Na 2 SiO 3 × 9H 2 O and Na 2 SiO 3 in the Si–O vibrational range. It is known from X-ray structure analysis [] that the anhydrous sodium metasilicate is built up from chains of [–O–(SiO 2) 2− –O–] n tetrahedra, each sharing two oxygen atoms with their … WitrynaThe UV visible spectrum of the sample is as shown in fig 3. The sample absorbs the radiations in the UV range up to 361.75nm and almost all the visible spectrum radiations are transmitted by the ZnO nanoparticles. The band gap of the ZnO nanoparticles was calculated by extrapolating the curve drawn between (h ν) and (α hν) 2(shown in fig 4 ...
