Luminous nano composite material and its preparing method

Abstract

A nano-class composite luminescent material for effectively converting the ultraviolet light to red fluorescence light is prepared from polymer (100 wt portions), clay (0.5-30), RE-organosilicon as optical converting agent (0.5-10), dispersing medium (20-400), cross-linking agent (0-10) and promoter (0-1) through the reaction between nitrate or hydrochloride of Eu or Tb, organic carboxylic acid and organosilicon surfactant for 3-6 hr, the reaction between organosilicon-type optical converting agent, clay and dispersing medium to obtain organic clay compound, dispersing in polymer, stirring, adding cross-linking agent and promoter, and moulding for 0.2-24 hr.

Description

technical field

[0001] The invention relates to a nano-luminescent composite material and a preparation method thereof, in particular to a polymer / rare earth organosilicon light-transforming agent-clay nano-luminescent composite material and a preparation method thereof. Background technique

[0002] my country is a country rich in rare earth resources, possessing 80% of the world's exploitable rare earth reserves. The rare earth resources are widely distributed, with many varieties and complete elements. It is of great significance to deeply process rare earth resources into new functional materials with high added value. At present, the research on luminescent materials has become a hot spot in the field of scientific research, especially in recent years, interdisciplinary and new technologies have brought rare opportunities and challenges to the synthesis of luminescent materials. Polymer compounds play an important role in the transformation of rare earth fluorescent co...
