Abstract
Functional dyes allow optical applications of polymers in optical fiber technology. This paper presents a fabrication process and spectroscopic characterization of poly(methyl methacrylate) (PMMA) fiber doped by Spirooxazine (SO). The fabricated specimens at concentrations 0.4 to 0.8 wt. % have been characterized. The reversible absorption band with a maximum at 602 nm was observed under 365 nm exposition. The optical properties of PMMA-doped functional dye (photochromic and fluorescence) are presented in this paper. The kinetics of photochromic phenomenon is also investigated. The properties of polymeric fiber doped by SO are also presented since reabsorption effect changes the luminescence spectrum shape of SO.
