. The crystal structure and the luminescent properties of the samples are measured and characterized by using the method of DTA-TG
IR
powder XRD and excitation and emission spectra
respectively. The DTA-TG analysis shows that the weightlessness is obvious in the temperature range of 50~400 ℃
and this phenomenon corresponds to the loss of dissociated water
ethanol and acetic acid. The IR spectra shows that the samples are mostly composed of the TiOSi and OSiO bonds. Powder XRD analysis indicates that the samples are non-crystal material. The excitation and emission spectra show that the best annealing temperature is 800 ℃ for preparing material and the optimum Eu

. It also shows that the best excitation lights are the ultraviolet light with the wavelength of 395 nm and the visible light with the wavelength of 465 nm when the wavelength of the monitoring light is 612 nm
that is to say
the monochromaticity and the luminescent intensity of red light excited from the samples are optimum and basically the same when the wavelengths of the excitation lights are 395 nm and 465 nm
respectively.
