Emission spectra of diiodine-substituted boron dipyrromethene (I2BODIPY) dye in ethanol solutions and in methylcellulose matrix were studied. The solid patterns were photoexcited at 520 nm and display room temperature phosphorescence with a maximum at 790 nm that is quenched by molecular oxygen at room temperature. Novel sensing material for oxygen concentration detection from 0% to 100% has been developed on the basis of I2BODIPY with 17-fold sensitivity (I-Ar/I-O2), reverse, fast response (1 s) and linear calibration. The sensitivity dependence on the active substance concentration in matrix was shown.
