摘　　要：采用同时测量红绿蓝(RGB)三种颜色的数字颜色芯片,实现了一种同步监测氧气和温度的便携式传感器。涂覆于颜色芯片上的传感膜由三种荧光染料嵌入有机改性硅溶胶凝胶基质构成。所有染料均用405 nm的发光二极管光源激发,其荧光波长分别与颜色芯片的RGB三个通道相匹配且无光谱交叠。不同氧气浓度和温度下的实验结果表明,所研发的传感器能有效地同步监测氧气和温度,且在氧气浓度为0%~30%和温度为25~75℃时具有良好的线性响应。This study realizes a portable sensor for dual sensing of oxygen and temperature using a digital color chip with a simultaneous measurement function of three colors, namely, red-green-blue(RGB). An ormosil sol-gel matrix is doped in the sensing film coating on the color chip with three fluorescent dyes. All dyes are excited using a 405-nm light-emitting diode. The emission wavelengths match the three RGB channels of the color chip separately without a spectral overlap. Under various temperatures and oxygen concentrations, the experimental results show that the developed sensor allows a simultaneous monitoring of both temperature and oxygen with good stability and has an excellent linear response in the oxygen concentration range of 0%-30% and the temperature range of 25-75 ℃.
