Abstract

The invention discloses a method for preparing an inorganic/organic nano-composite luminescent material, which comprises the following steps: weighing metal oxides, V-group metal compounds or VI-group metal compounds with a particle size of nanometers, and putting them into a cleaned container; preparing Organic dye solution or organic dye intermediate solution; added to the container, ultrasonic-heating and reflux treatment; suction filtration, filter cake washed with ethanol or water to remove excess organic matter that is not bonded on the surface of the nano-powder, and dried to obtain Inorganic/organic nanocomposite luminescent materials. The present invention uses nano powder as raw material to prepare composite material, which can retain the specific properties of nano material, and its application is more extensive; the method is simple and easy, with low operating temperature and short processing time; the applicable material of the present invention There are many systems; the present invention is compounded in a low-temperature uniform liquid phase, thus ensuring sufficient bonding between organic and inorganic materials.

Description

technical field [0001] The invention belongs to the field of functional materials and relates to a preparation method of a nanocomposite luminescent material. Background technique [0002] Nanomaterials refer to materials with at least one phase in the microstructure of the material whose one-dimensional scale is within 100nm. Due to the small average particle size, many surface atoms, large specific surface area, and high surface energy of nanomaterials, their properties are different from single atoms, molecules, and ordinary granular materials, showing unique small size effects, surface effects, etc. It has properties that many conventional materials cannot have. It is precisely because of the large number of atoms on the surface of nanomaterials and the lack of adjacent atoms around the surface atoms, which leads to unsaturation of atomic coordination and high surface energy, making these surface atoms more active and easily combined with other atoms. Nanomaterials hav...
