- Abstract:
- Variations in the photoluminescence (PL) spectra from porous silica gel containing the luminous organic pigments were evaluated before and after the exposure in the vapors of CHCl3. Peak intensity of PL from rhodamine and fluorescein contained silica gel vary with the concentration of pigment. Peak intensity of PL also varies after exposure in the organic vapors of CHCl3. Temperature dependences of PL intensity from rhodamine and fluorescein contained silica gel are also evaluated for sensor applications. The organic luminous pigments contained silica gel is suggested to be useful fluorescent sensor materials.
