摘要	A series of organic-inorganic hybrid composites were prepared from methyltriethoxylsilane (MTEOS) /tetraethylorthosilane (TEOS) xerogels chemically doped with a Ru(II) complex. The effect of MTEOS/TEOS molar ratio on the luminescence and oxygen sensing properties has been systematically investigated based on the luminescence intensity quenching. Moreover, the effects of MTEOS/TEOS molar ratio on the structure change in the matrix and the bonding between the probes and the matrix were studied by Fourier transform infrared spectroscopy (FTIR) and electronic absorption spectra etc in detail for a better understanding of the oxygen sensing behaviors. The experimental results show blue shift in the emission wavelength of Ru(II) complex entrapped within MTEOS/TEOS compared with that in the pure silica matrix. And the oxygen sensitivity was found to increase with increasing molar ratio of MTEOS to TEOS owing to the decreased polarity of the microenvironment around the Ru(II) molecules, Leaching study was also performed for testing the bonding between the probes and the xerogel matrix, which shows that parts of the indicator dyes would elute from the matrix for the xerogel containing more than 20% MTEOS because of less Si-OH groups with which the dyes could react to form covalent bond.
