Optical Characterization of Chemically Etched Nanoporous Silicon Embedded in Sol-Gel Matrix

Figure 4

Emission spectra of NPs in sols (liquid) Such solvent may help the intensity variation of NPs Si in sol-gel host. However, DMF used as DCCA may help to form better sol-gel quality in terms of monolithicity, transparency, low density, and control the rate of evaporation during aging. The peak positions of NPs Si in THF, sol and sol-gel solid are summarized in Table 1.
