Embodiment 1

[0025] 1. Preparation of 3-(trimethoxysilyl) propyl acrylate hydrosol

[0026] Mix 1mL of 3-(trimethoxysilyl)propyl acrylate with 115uL of distilled water with a pH value of 2, adjust the pH value of the distilled water with hydrochloric acid, leave it to age at room temperature for 6 hours, and obtain 3-(trimethoxysilyl base) propyl acrylate hydrosol.

[0027] 2. Preparation of europium acrylate-organic silica sol

[0028] Dissolve 1.6 g of europium acrylate completely in 2 mL of dimethyl sulfoxide, then add 1.0 g of 3-(trimethoxysilyl)propyl acrylate hydrosol and 0.1 g of 2,4,6-trimethylbenzoyl-di Phenylphosphine oxide, uniform ultrasonic dispersion, to obtain europium acrylate-organic silicon sol.

[0029] 3. UV curing

[0030] The acrylate europium-organosilicon sol obtained in step 2 was irradiated with an ultraviolet surface light source with a wavelength of 365nm for 10 minutes, wherein the distance between the sample and the light source was 20cm to obtain a transpa...

Embodiment 2

[0032] In step 2 of the preparation of europium acrylate-organic silica sol in this example, 0.05 g of europium acrylate was completely dissolved in 0.25 mL of dimethyl sulfoxide, and then 1.0 g of 3-(trimethoxysilyl) propyl acrylate hydrosol was added and 0.06g of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, and dispersed uniformly by ultrasonic to obtain europium acrylate-organic silicon sol. Other steps were the same as in Example 1 to obtain a uniform and transparent europium-bonded fluorescent gel glass.

Embodiment 3

[0034] In step 2 of the preparation of europium acrylate-organic silica sol in this example, 0.33 g of europium acrylate was completely dissolved in 0.4 mL of dimethyl sulfoxide, and then 1.0 g of 3-(trimethoxysilyl) propyl acrylate hydrosol was added and 0.06g of 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, and dispersed uniformly by ultrasonic to obtain europium acrylate-organic silicon sol. Other steps were the same as in Example 1 to obtain a uniform and transparent europium-bonded fluorescent gel glass.

Abstract

The invention discloses a light-curing preparation method of rare earth bonded fluorescent gel glass. According to the method, organosiloxane containing dual functional groups is used as a sol-gel precursor, and a rare-earth complex is bonded to a gel glass matrix in an ultraviolet light curing manner, thus the rare earth bonded fluorescent gel glass is prepared. Compared with the traditional thermal polymerization methods, the method disclosed by the invention has the advantages of simplicity and easiness in operation, short reaction time and environmental friendliness, and the prepared rare earth bonded gel glass is uniform and transparent, has good thermal stability, is prone to machine-shaping, is suitable for industrial production and has a broad application prospect in the field of photovoltaic cells or lighting.

Description

technical field [0001] The invention belongs to the technical field of rare earth polymer composite luminescent materials, and in particular relates to a preparation method of rare earth bonded fluorescent gel glass cured by ultraviolet light. Background technique [0002] Rare earth elements have the reputation of "industrial vitamins", and now they have become extremely important strategic resources. my country's rare earth production and reserves rank first in the world, so the research on rare earth materials has very important application value. For example, rare earth luminescent materials have been widely used in optics, optoelectronics, supramolecular chemistry, biomarkers and other fields. In order to improve the light and thermal stability of rare earth complexes and expand the application of rare earths in the preparation of light conversion molecular devices, organic light-emitting devices and other fields, the rare earth complexes are fixed on inorganic or orga...
