摘 要: 氧指示剂的光降解是影响荧光猝灭氧传感器光稳定性的主要因素 .本文研究了 Ru(dip) 2 + 3络合物氧敏感膜光降解模型 ,给出了敏感膜光降解速率与激励光波长。 Photobleaching of oxygen sensitive membrane is the key factor to influence the photo stabilization of the fluorescence quenching based oxygen sensors. Using laser source and home made heater control circuit, we study the photobleaching model and investigate the characters of wavelength dependance, intensity dependance and temperature dependance of Ru(dip)\+\{2+\}\-3 based oxygen sensitive membrane.
