Core/shell hybridized nanocrystals composed of Ag nanoparticle core and polydiacetylene shell were fabricated successfully by means of "co-reprecipitation/microwave irradiation method". The hybridized nanocrystals were characterized using transmission electron microscopy (TEM) observation and UV-vis absorption spectroscopy. UV-vis spectral measurements revealed that polydiacetylene shell was the red phase while π-conjugated backbone is distorted. Detailed mechanism of formation of the red phase was discussed.
