Problems solved by technology

[0007] [7] However, the technology disclosed in Patent Document 1 utilizes reinforcement on thin films and is limited to samples (ultra-thin films on thin metal films)
However, particles generating enhanced surface plasmon fields sensitize single-photon absorption and the field of application is limited to fine particles
Therefore, this technique has the following disadvantages: for practical use, limited wavelengths can be used and application fields are limited
[0021] [21] However, the transition efficiency of such simultaneous two-photon absorption is much lower than that of single-photon absorption, and two-photon absorption requires photon
[0036] [36] However, Patent Documents 6 and 7 do not describe specific two-photon-absorbing materials, but theoretically describe two-photon-absorbing compounds such as two-photon-absorbing compounds with extremely small two-photon absorption efficiencies
[0037] [37] In addition, the photochromic compounds used in Patent Documents 8 and 9 are reversible materials, and there are problems of non-destructive readout, long-term archivability of recording, S / N ratio of reproduction, etc.
However, no method has been described for 3D optical recording media using two-photon absorption

Embodiment 1

[0183] [144] First, 70 mL of a 0.18 mol / L cetyltrimethylammonium bromide aqueous solution, 0.36 mL of cyclohexane, 1 mL of acetone, and 1.2 mL of a 0.1 mol / L silver nitrate aqueous solution were mixed and stirred. After adding 0.3 mL of 0.24 mol / L chloroauric acid aqueous solution, 0.3 mL of 0.1 mol / L ascorbic acid aqueous solution was added, and it was confirmed that the color of chloroauric acid disappeared. Then, the solution was transferred into a vessel and irradiated with ultraviolet light having a wavelength of 254 nm by a low-pressure mercury lamp for 20 minutes. Therefore, a gold nanorod dispersion solution with an absorption peak wavelength of about 800 nm is obtained. The dispersed solution was placed in a centrifuge to separate and precipitate gold nanorod components. The supernatant was removed and water was added to the dispersion solution. Repeat centrifugation several times to remove excess cetyltrimethylammonium bromide dispersant.

Embodiment 2

[0185] [145] First, 70 mL of a 0.18 mol / L aqueous solution of cetyltrimethylammonium bromide, 0.36 mL of cyclohexane, 1 mL of acetone, and 1.0 mL of a 0.1 mol aqueous solution of silver mononitrate were mixed and stirred. After adding 0.3 mL of 0.24 mol / L chloroauric acid aqueous solution, 0.3 mL of 0.1 mol / L ascorbic acid aqueous solution was added, and it was confirmed that the color of chloroauric acid disappeared. Then, the solution was transferred into a vessel and irradiated with ultraviolet light having a wavelength of 254 nm by a low-pressure mercury lamp for 20 minutes. Therefore, a gold nanorod dispersion solution with an absorption peak wavelength of about 760 nm is obtained. The dispersed solution was placed in a centrifuge to separate and precipitate gold nanorod components. The supernatant was removed and water was added to the dispersion solution. Repeat centrifugation several times to remove excess cetyltrimethylammonium bromide dispersant.

Embodiment 3

[0187] [146] First, 70 mL of a 0.18 mol / L cetyltrimethylammonium bromide aqueous solution, 0.36 mL of cyclohexane, 1 mL of acetone, and 1.5 mL of a 0.1 mol / L silver nitrate aqueous solution were mixed and stirred. After adding 0.3 mL of 0.24 mol / L chloroauric acid aqueous solution, 0.3 mL of 0.1 mol / L ascorbic acid aqueous solution was added, and it was confirmed that the color of chloroauric acid disappeared. Then, the solution was transferred into a vessel and irradiated with ultraviolet light having a wavelength of 254 nm by a low-pressure mercury lamp for 20 minutes. Therefore, a gold nanorod dispersion solution with an absorption peak wavelength of about 840 nm was obtained. The dispersed solution was placed in a centrifuge to separate and precipitate gold nanorod components. The supernatant was removed and water was added to the dispersion solution. Repeat centrifugation several times to remove excess cetyltrimethylammonium bromide dispersant.

Abstract

A photosensitized composite material and a material, an element, a device, and the like, which employ the photosensitized composite material, are provided. In the photosensitized composite material, multiphoton absorption compounds are highly sensitized for practical use by utilizing an enhanced plasmon field. The photosensitized composite material has a structure where the multiphoton absorption compounds are linked to the surface of a fine metal particle through linking groups. The fine metal particle generates an enhanced surface plasmon field in resonance with a multiphoton excitation wavelength. The multiphoton absorption compounds have a molecular structure enabling multiphoton absorption. The photosensitized composite material is contained in or used for, for example, a three-dimensional memory material and a three-dimensional recording medium, an optical power limiting material and an optical power limiting element, a photocuring material and a stereolithography system, and a fluorescent material for a multiphoton fluorescence microscope and a multiphoton fluorescence microscope.

Description

technical field [0001] [1] The present invention relates to multiphoton absorbing materials, and more particularly to photosensitive composite materials exerting a high sensitization effect, and their effects on materials, device electronic components, etc. (three-dimensional storage materials and three-dimensional recording media, optical power confinement materials and optical power confinement components, photocurable materials and stereolithography systems, and applications of fluorescent materials for multiphoton fluorescence microscopy and multiphoton fluorescence microscopy). Background technique [0002] [2] Two-photon absorption, a type of multiphoton absorption, can be used in a variety of applications characterized by extremely high spatial resolution. Until now, available two-photon absorbing compounds have low two-photon absorption rates. An expensive, very high-power laser must therefore be used as a pump source to induce two-photon absorption.
