engineering of semiconductor nanocrystals for light emitting applications - led display signs

Semiconductor nanoparticles are rapidly entering the display and lighting market.
Compared with liquid crystal and organic LED display, nano crystal quantum dots (QDs)
Provides highly saturated color, wide color range, resolution, fast response time, optical efficiency, durability and low cost.
This significant progress has become possible as the synthesis of colloidal QDs has made rapid progress and progress has been made in understanding the interesting new physics presented by these nanoparticles.
In this review we support the idea of properly designing the core/grading
Shell layer QDs have excellent optical properties, luminous properties and optical gain, while maintaining the simplicity of synthesis and the production of QDs are ideal for light-emitting applications. Solid-
As an efficient gain material, solid-state laser transmitters can get huge benefits from QDs.
Progress in manufacturing DFB lasers with low threshold and solution treatmentand two-
Photon absorption is reviewed.
In the field of display technology, the development of special luminous properties for LCD backlight has developed to a commercial level.
The next big challenge is to develop the luminous properties of QD to a similar state.
We present an overview of QLED devices, as well as a huge prospect for next-generation display and lighting technologies.
