Abstract(in Japanese) (See Japanese page)
Abstract(in English) We report an amplified blue light-emission from self-organized one-dimensional crystals of p-sexiphenyl molecules. The crystals vapor-deposited on the KCl(001) surface by hot-wall epitaxy grow in needles with a submillimeter length, in which the molecular axes epitaxially orient along the[110] direction of the KCl substrate. Under ultraviolet pulse laser excitation, the blue light-emission is self-waveguided along the needle axis and gain-narrowed at the vibronic bands of p-6P. This amplified emission radiated from the tips of the needles is polarized with the transverse-electric(TE) mode based on the uniaxially oriented transition dipoles which are aligned perpendicular to the needle axis.
