Abstract
Ammonia detection is one of the actual problems in food packaging applications. This paper presents the results of the study of optical sensors of ammonia vapor based on novel organic pyridine lumino-phores modified with acids. Optical, structural properties of luminophores at room temperature were investigated. The sensitivity of the luminophores to ammonia vapor in the 20-700 ppm concentration range was investigated.
