| Outline of Final Research Achievements |
It was revealed that the spherical porous silica containing carbon could be successfully synthesized by using tannic acid and aminosilane. It was also found that these porous silicas exhibited broad photoluminescence spectra in the visible light region by UV light excitation. Moreover, it was clarified that these colloidal crystals could be prepared from the spherical porous silica nanoparticle dispersion by ultra low speed dip coating method.
We revealed the possibility of fabricating a light emitting device with controlled wavelength only with silica.
