QD Luminescent material is inorganic semiconductor micro crystal particles with fluorescence characteristics and based on 1-20 nanometer scale.This kind of quantum dot can control electronic in a small three-dimensional space.When the excitation light illuminates,electrons will be excited to jump to a higher energy level.When the electron returns to the original lower energy level,it will emit a beam of certain wavelength and color.It will produce fluorescence properties.Different materials and particle size can produce red / Blue / green and other colors fluorescence.
Our company now has the sulfide,selenide,telluride and carbon series peninsula quantum dots（Ⅱ-Ⅵ）.We can provide liquid and solid material.Main application:LED lighting, LCD display, fluorescent anti fake, biological marker, ultra-thin electronic luminescence, solar cells, plant growth, etc..

Electroluminescent Phosphor ( EL ) is a inorganic material that converts electric energy to lights directly, being widely applied to EL glass panel, enamel panel, plastic panel , EL wire , DC and AC EL lighting instruments . its main glowing color include Blue, Green, Orange, and their transition color.
As now main EL panel making tech apply screen printing and spray, EL phosphor we manufacture are divided into 3 types as below:
TYPE B: Average particle size 29μm, high brightness, heat resistance, suitable for application to plastic and enamel panel.
TYPE S: Average particle size 9μm, better brightness, homogeneous emitting effect, suitable for application to glass and plastic panel.
TYPE CT: Average particle size 28μm, With characteristic of particle surface being coated, it has good humidity resistance, prolonged application lifetime , high brightness, no need of sealed package, suitable for application to plastic panel.

The elastic luminescent material is made up of inorganic luminescent micro crystalline powder. The luminescence of elastic luminescent materials is mainly due to the electret effect of micro crystalline luminescent materials. Of course, micro crystalline luminescent materials can produce instantaneous visible radiation when it has elastic deformation or plastic deformation which can not be resumed. When the colloid mixed with the luminescent material, the colloid is rubbed with the surface of the luminescent crystal and then cause accumulated electric charge to form the excited electron transition state and then produce visible light radiation.
It can be used for elastic sensor, pressure sensor, friction sensor and electrostatic sensor.
