Luminescent QD Material


QD Luminescent material is inorganic semiconductor micro crystal particles with fluorescence characteristics and based on 1-10 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.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..
