Abstract
The development of optical sensors generates interest for multiple applications in the measurement of parameters such as pH. Results of the optical characterization of an organic material used as a sensitive element for pH measurement are presented. The characterized material is Lofin (2,4,5-triphenyl-1H-imidazole), it shows changes in its absorbance at the wavelength of 505 nm when subjected to pH variations. The study includes an analysis based on the concentration of this material in a polymeric matrix and its absorbance.
