Scientists and engineers always push the limits to design or improve optical sensors for lower cost, lower power consumption and high portability without sacrificing the sensors sensitivity and selectivity. This dissertation centers on the development and improvement of two optical gas sensors. The research is divided into three main topics: (1) the characterization of a new pH responsive photonic ionic liquid for ammonia and simple amine vapor detection, (2) the examination of proton transfer dynamics between the pH responsive photonic ionic liquid and acidic/basic vapors, and (3) the investigation of analytical figures-of-merit for a hybrid oxygen responsive reflective Bragg grating platforms. Each Chapter is designed to stand alone so the reader can read any Chapter in any order without having to refer to other Chapters.
