Definitions

  • the metal oxide nanoparticles may contain, for example, a UV-polymerizable functional group. This allows the metal oxide nanoparticles to be properly bonded in the acrylate resin when the resin is cured by UV irradiation.
  • the metal oxide nanoparticles may also be surface-modified (coated) with an oleophilic dispersant or the like.
  • the surface-modified metal oxide nanoparticles may be, for example, a dispersion liquid (resin A) that is blended and dispersed in a liquid acrylate resin (organic solvent) separate from the acrylate resin containing the fluorene skeleton described below.
  • the acrylate resin (resin B; first acrylate resin) has a fluorene skeleton.
  • the fluorene skeleton has an aromatic ring with a three-ring structure.
  • the fluorene skeleton has a large number of C-C bonds derived from the aromatic ring, and therefore has high thermal stability.
  • acrylate resins with a fluorene skeleton have a slightly high refractive index (e.g., 1.58).
  • this resin B has ether (or C-O-C) bonds. If there are many ether (or C-O-C) bonds in the polymer resin, the flexibility of the resin improves according to the interactions between molecules.
  • the ratio of each component in the cured product obtained from the photocurable composition containing these components can be obtained using infrared spectroscopy.
  • Infrared spectroscopy is a technique that uses the fact that infrared light irradiated to an object is absorbed in a wavenumber band (wavelength, frequency) corresponding to the components and structural parts (functional groups, etc.) of the object to identify the components and their amounts from the characteristics of the absorbed wavelength and the intensity of the absorption (absorbance).
  • an offset may occur in each measured value (absolute value) (especially in the microscopic ATR method described below).
  • a line located on both sides of the range including the wavenumber band of the object for which absorbance is detected and connecting the absorbance at wavenumbers where absorption is expected to be low is used as a reference line, and the area occupied by the reference line and the distribution of absorbance measured in the wavenumber band of the object for which absorbance is detected is obtained as a value corresponding to the amount of the component.
  • the metal oxide nanoparticles (resin A) contain O-H bonds as described above, infrared light is absorbed in a wide range of 3100-3700 cm -1 according to the O-H bonds. On both sides of this region, 1790 cm -1 and 3720 cm -1 are assumed to be the minimum points of absorption (in actual measurements, the minimum points may be shifted slightly, and the above two minimum points may be fixed regardless of the shift).
  • the light-emitting device 1 of the present disclosure also includes the optical component 10. Such a light-emitting device 1 can widely diffuse and radiate the emitted light. Therefore, the light-emitting device 1 can be used more reliably and widely in applications that require illumination over a wide area.
  • the UV curing agent is added in addition to the resins A to C, but other components may be further included.
  • the other components may include acrylate resins other than the resins A to C.
  • the specific materials, components, structures, amounts and ratios shown in the above embodiments can be appropriately changed without departing from the spirit of the present invention.
  • the scope of the present invention includes the scope of the invention described in the claims and its equivalents.
  • This disclosure can be used in optical components, light emitting devices and modules.
