Sergey Krutovertsev, Alexander Borisov, Maxim Chuprin, Olga Ivanova & Stanislav Kuleshov
A particular place among optical methods of analysis is occupied by chemical sensors based on effect of frustrated total internal reflection and thin films of substances, which alter their optical features under effect of environment contents. It is known, that some organic substances are sensitive for gases micro-concentrations at a room temperature, for example, organic dyes. Many pH dyes have been inserted in sol-gels for the pH sensing and acid-base gases including CO2 and NH3....
