Nano coatings have been successfully applied to improve the efficiency of LED equipment

A method which can make more transparent glass or similar materials can improve the efficiency of LED equipment, such as flat screen etc..

The project by University of London Kings College doctoral student Ryan McCarron for leadership, the success of the gold nano film into glass, with light scattering.

Generally speaking, in the perspective of the increasingly sharp, flat TV and other equipment installed LED is considered to be the quality of decline, from an aesthetic point of view, this is only limited the efficiency of these devices.

"If a glass or other material other than the light emitting layer is used on an interface, a large portion of the light will be trapped in the interior. "McCarron told the engineer," whenever a beam of light passes through a certain angle, the critical angle, all the light is reflected, not through. "

So only a small range of beams can be transmitted, the actual transmission rate is much lower than the theoretical. "

His solution to this problem is to paint a layer of nano paint on a glass in a particular shape. This method promotes the scattering by manipulating the surface plasma between the contact surfaces of the material.

The surface plasma is the intermediate phase of the two sides of the grating, which can be separated from the other side through the propagation of the grating.

Currently, the project team is using metal gold as raw materials, McCarron said that although it is easy to operate, but this method is also applicable to aluminum and other cheaper materials, can save costs.

McCarron said that this method can be used in many other applications, such as biochemical sensing technology, integrated optoelectronics, photovoltaic cells and organic LED, etc..
