摘要:
A method for multiphoton-ionizing an organic molecule supported by a solid carrier according to the present invention is a method characterized in that the carrier supporting an organic molecule is irradiated with a laser light having a pulse width of less than 1 nanosecond. As a laser having a pulse width of less than 1 nanosecond, such femtosecond lasers as titanium-sapphire lasers, fiber lasers and ytterbium-tungsten lasers are desirable.

A detection unit of an optical pickup apparatus includes an optical element to simultaneously extract plural specified lights having a different polarization direction respectively in a separated state from light from an optical recording medium, and a light amount measurement unit to simultaneously perform light amount measurement on each of the plural specified lights extracted by the optical element. At the time of reproduction of information, reflected light from the optical recording medium in the case where reproducing light is irradiated, or emission light emitted from the optical recording medium by irradiation of reproducing light is sent to a detection unit. The optical element extracts the plural specified lights having the different polarization direction respectively in the separated state, the light amount measurement unit simultaneously performs the light amount measurement on each of the plural specified lights extracted by the optical element, and the information recorded on the optical recording medium is reproduced from the ratio of light amounts.
摘要:
A recording layer of an optical recording medium is made of a polymer film containing a polymer solid, such as polymethyl methacrylate, as a main ingredient. The polymer film contains a dye to absorb light having a specific wavelength band, and the optical recording medium exhibits anisotropy in at least one of light absorption intensity and emission intensity by irradiating the recording layer with a linearly polarized light having the specific wavelength band and an arbitrary polarization direction. It is preferable that the specific wavelength band is included in a wavelength region of 350 nm to 450 nm.

By multiplexing light-harvesting layer and complexing with hole transport films or electron transport films, a photoelectric device and a solar cell exhibiting highly efficient electricity generation property can be obtained. A composite layer (11) in a photoelectric device (31) includes: a 1st light-harvesting film (A1) that includes photosensitive groups which absorb light energy and are excited thereby; a 1st hole transport film (P1) containing electron-donating groups that donate electrons to photosensitive groups; an nth light-harvesting film (An) that includes photosensitive groups which absorb light energy that has passed through an (n−1)th light-harvesting film (An−1) and are excited thereby; an nth hole transport film (Pn) that is sandwiched between the nth light-harvesting film (An) and the (n−1)th light-harvesting film (An−1) and includes electron-donating groups for donating electrons to the excited photosensitive groups; light-harvesting film connectors (41) that connect the (n−1)th light-harvesting film (An−1) and the nth light-harvesting film (An); and hole transport film connectors (42) that connect an (n−1)th hole transport film (Pn−1) and the nth hole transport film (Pn).
