Embodiment A-1

[0345] 10 g of silver nitrate and 37.1 g of oleylamine (85%) were added to 300 ml of toluene and stirred for 1 hour. Then, 15.6 g of ascorbic acid was added and stirred for 3 hours. Next, 300 ml of acetone was added, the supernatant was removed by decantation, and the solvent contained in the precipitate was distilled off to obtain spherical silver fine particles with a diameter of 10 nm to 30 nm.

[0346] 1 mg of the obtained spherical silver fine particles was redispersed in 10 ml of toluene, and then 7 mg of the two-photon fluorescent dye represented by formula (1) was added and stirred.

[0347] Formula 1)

[0348] After the dye was dissolved, 1 g of acrylic resin DIANAL BR-75 (from MITSUBISHI RAYON CO., LTD.) was added and stirred to dissolve. The resulting solution was poured into a frame formed on a glass substrate. The solvent was evaporated for solidification, yielding a block composed of spherical silver fine particles and two-photon fluorescent dye-dispersed ac...

Embodiment A-2

[0350] 1 mg of the spherical silver fine particles obtained in Example A-1 were redispersed in 10 ml of toluene, and mixed with a toluene solution of 0.2 g of 1 mass % polyethyleneimine (from NIPPON SHOKUBAI CO., LTD., with an average molecular weight of 300) Upon mixing, small aggregates of spherical silver fine particles were confirmed by the color change of the dispersion.

[0351] Further, 7 mg of a two-photon fluorescent dye represented by formula (1) was added and stirred to dissolve in the solution, and then 1 g of acrylic resin DIANAL BR-75 (from MITSUBISHI RAYONCO., LTD.) was added and stirred to dissolve. The resulting solution was poured into a frame formed on a glass substrate. The solvent was evaporated for solidification, yielding a block composed of aggregated spherical silver fine particles and two-photon fluorescent dye-dispersed acrylic resin and having a thickness of 50 μm.

Embodiment A-3

[0353] Chlorauric acid (0.37 g) was added to 30 ml of water, and then a mixed solution of 2.187 g of tetraoctylammonium bromide and 80 ml of toluene was added and stirred for 2 hours.

[0354] Furthermore, 0.2 g of 1-dodecanethiol was added and stirred for 1 hour.

[0355] After that, 0.378g NaBH was added dropwise 4 The solution was dissolved in 20 ml of water and stirred for 2 hours.

[0356]The reaction product was washed several times with water using a separatory funnel, and then the solvent of the organic layer was distilled off to obtain spherical gold fine particles with a diameter of 20 nm to 50 nm.

[0357] 3 mg of the obtained spherical gold fine particles were redispersed in 10 ml of toluene, then 7 mg of a two-photon fluorescent dye represented by formula (1) was added and stirred to dissolve in the solution, and 1 g of acrylic resin DIANAL BR-75 (from MITSUBISHI RAYON CO., LTD.) and stir to dissolve. The resulting solution was poured into a frame formed on a g...

Abstract

A multiphoton absorption functional material including one of: fine particles of metal, and fine particles partly coated with the metal, the metal generating enhanced surface plasmon field on a metal surface, wherein the fine particles or the fine particles partly coated with the metal are dispersed in a multiphoton absorption material, and wherein the multiphoton absorption functional material is a bulk body.

Description

technical field [0001] The present invention relates to multiphoton absorption functional materials, composite layers and mixtures with multiphoton absorption functions, and optical recording media, photoelectric conversion elements, Optical control elements and optical modeling systems. [0002] The present invention also relates to a sensitization technique of a multiphoton-absorbing organic material utilizing a localized enhanced plasmon field generated in metal fine particles, and a functional device using the technique. Background technique [0003] It is known that two-photon absorption, a type of multiphoton absorption process, can cause a reaction only at the focal point of a focused beam because the reaction is induced by absorbing a photon with a probability proportional to the square of the excitation light intensity Yes, this is characteristic of two-photon absorption. [0004] In other words, since a reaction can be induced only at any desired point in the mat...
