Preparation of photo functional material

摘要

DNA polymer gel was prepared by combining DNA-lipid and polymer gel. A hemicyanine dye, trans-4-{4-(dibutylamino)-styryl}-1 methylpyridinium iodide (DBASMPI) doped DNA polymer gel was obtained by soaking it in dye solution. We observed optical properties of dye-doped DNA polymer gel. Amplified spontaneous emission (ASE) properties of dye-doped DNA polymer gel at ambient temperature were investigated. We measured the intensity of output light from samples as a function of pump pulse energy in order to determine the threshold energies. The emission spectra were obtained under several values of excitation intensity to confirm spectral narrowing. We discussed the lasing capability by dye-doped DNA polymer gel.
