Variations in the optical properties of poly(3-hexylthiophene)/C(sub 60) blends and poly(3-hexylthiophene)/sol-gel composites

摘要

We report the synthesis and characterization of thin films of poly(3- hexylthiophene) (P3HT)/C(sub 60) blends. UV-V is spectra of the P3HT/C(sub 60) blends with various amounts of C(sub 60) show significant blue shift, which indicates the complex formation between P3HT and C(sub 60). A new type of luminescent glass was also prepared by sol-gel technique. This method allows incorporation of P3HT (photoemissive polymer) into the sol-gel matrix and results in glasses that feature stimulating photoluminescent properties. By slightly varying the synthetic conditions of fabricating these P3HT/sol-gel glasses, we can control their emission colors from blue to red, covering the whole visible spectrum.
