- W2370436699 abstract "In this paper, the tetraethoxysilane (TEOS) precursor is hydrolyzed with ethanol as co-solvent under various concentrations of hydrochloric acid catalyzer to prepare the alkoxysilane pre-polymer solutions containing the luminescent Ru(dpp) 2+ 3 complex through sol-gel process. A series of oxygen-sensing films were fabricated by spin coating of such pre-polymer solutions onto glass slides followed by aging and drying of resultant gels. The effects of acid catalyzer concentration on the micro-structures of sol-gel matrices and the micro-environments of luminescent molecules are revealed by the luminescent quenching behaviors of Ru(dpp) 2+ 3 complex within such sol-gel matrices under various oxygen concentrations.It is shown that the maximum emission peak of Ru(dpp) 2+ 3 in sol-gel matrices is almost independent on the acid catalyzer concentration, suggesting that very dinky change of chemical micro-circumstance around Ru(dpp) 2+ 3 complex can induced. Compared in ethanol solution, the emission peak of Ru(dpp) 2+ 3 in solid state exhibits a red shift for about 14nm, and the red shift for Ru(dpp) 2+ 3 in sol-gel matrix is only 4nm, suggesting that such matrices are excellent dispersoid for Ru(dpp) 2+ 3 complex. The quenching responses of all prepared oxygen sensors generally exhibit excellent stability, reproducibility and high signal-to-noise ratio. The sensor performances such as quenching response Q, Stern-Volmer coefficient K SV and response times (both quenching time t Q and resuming time t R) are improved with decreasing acid catalyzer concentrations. Since the acid catalyzer concentration has almost no effect on the chemical micro-circumstance around Ru(dpp) 2+ 3 complex, it seems that these improvements of sensor performance are mainly due to faster diffusion rate of oxygen in sol-gel matrices and higher collisional probability of oxygen with Ru(dpp) 2+ 3. Two facts may contribute to such improvements: firstly, the sol-gel matrices with more open and porous structures are favored when lower concentration of acid catalyzer is used; secondly, the polar Si-OH groups that have strong interaction with oxygen may be partially replaced by negative SiO - that cannot absorb oxygen under lower concentration of acid catalyzer." @default.
