Problems solved by technology

When resin is used as the sealing material, when the wavelength of the excitation light is converted by the phosphor, part of the energy is converted into heat, so there is a problem that the resin is discolored by the heat.
In addition, the resin has poor water resistance and easily permeates water, so there is a problem that the phosphor is easily deteriorated.

Embodiment 1

[0051] As inorganic nano phosphor particles, particles having a core-shell structure of CdSe (core) / ZnS (shell) and particle diameters of 3 nm (green) and 6 nm (red) were used. Here, about 50 organic molecules having an aliphatic hydrocarbon group having 10 carbon atoms are attached to one inorganic nano-phosphor particle as an organic protective film on the surface of the inorganic nano-phosphor particle. A dispersion liquid containing 1% by mass of the inorganic nano-phosphor particles in octane as a dispersion medium is impregnated into the glass powder (composition (mass ratio) SnO 72%, P 2 o 5 28%, average particle diameter D50: 4 μm, softening point: 290°C) preform (compact powder), remove the dispersion medium, thus the preform of glass powder with inorganic nano phosphor particles adhered can be produced. The mass ratio of glass powder to inorganic nano phosphor particles (glass powder:inorganic nano phosphor particles) is 50:1.

[0052] The preform of the glass pow...

Abstract

Provided are: a process for producing a wavelength conversion member, the process being capable of inhibiting the reaction of inorganic fluorescent nanoparticles with glass to inhibit the inorganic fluorescent nanoparticles from deteriorating; and the wavelength conversion member. The process is characterized by comprising a step in which inorganic fluorescent nanoparticles (1), the surface of which has been coated with an organic protective film, are prepared and a step in which the inorganic fluorescent nanoparticles (1) are mixed with a glass powder and the mixture is fired in a range of temperatures at which the organic protective film remains as a residual film (3).

Description

technical field [0001] The present invention relates to a method of manufacturing a wavelength conversion component and the wavelength conversion component. Background technique [0002] In recent years, light-emitting devices using excitation light sources such as light-emitting diodes (LEDs) and semiconductor lasers (LDs), irradiating phosphors with excitation light from these excitation light sources, and using the resulting fluorescence as illumination light have been studied. In addition, as phosphors, the use of semiconductor nanoparticles or inorganic nano phosphor particles called quantum dots has been studied. The inorganic nano phosphor particles can adjust the fluorescence wavelength by changing the diameter, and have high luminous efficiency. [0003] However, inorganic nano phosphor particles have a property that they are easily deteriorated when they come into contact with moisture or oxygen in the air. Therefore, the inorganic nano-phosphor particles must be...
