Recently learned from Hefei University of Technology, the school research team in the yttrium aluminum garnet series of LED fluorescent materials and light color control mechanism has made important achievements in order to further improve the performance of LED fluorescent material provides an important means.

High-power LED devices are widely used in public lighting and home and outdoor, however, when the LED lighting source is used for a long time, there will be dim brightness and color drift. Hefei University of Technology Materials Science and Engineering Associate Professor Chen Lei and Professor Jiang Yang task force on the issue of scientific research. Through a series of experimental methods combined with theoretical calculations, they provide a completely new explanation for the intrinsic mechanism of spectral red-shift, intensity reduction and thermal stability deterioration caused by Gd ion substitution. Due to the large Gd ion radius, the electron cloud is squeezed and deformed in the rigid structure of yttrium aluminum garnet, resulting in the enhancement of the crystal field, the reduction of the effective electron mass, the expansion of the electron spreading range and the reduction of the band gap, which leads to the decrease of the luminous efficiency And thermal stability is reduced. Recently, the research results published in the British "Nature" magazine, "Science Report" on.

According to reports, this theory not only scientifically explained the Gd substituted yttrium aluminum garnet phosphors luminescence phenomenon, but also for the development of new rigid structure of fluorescent material has an important guiding significance. "In the future, we can guide the development of man-made gemstone crystals with a specific color to give more brilliant colors, such as various artificial diamonds, sapphires and rubies, which not only show high light transmittance and reflectance, but also can be customized to make them bright and fresh Eye-catching. "Associate Professor Chen Lei introduction.

PVC Edge Banding For Furniture

The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.

The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.

Furniture edge banding is a material for protecting, decorating and beautifying the section of furniture panels. It can make a piece of furniture show the overall effect of clear wood grain and colorful.

PVC furniture edge banding is relatively light, which is relative to metal and plexiglass. The reason for the lightness is not because it is a polymer compound, but because they are organic compounds, which are composed of carbon, hydrogen, oxygen, and chlorine. And other lighter elements.
The material of pvc furniture edge banding is plastic, which is easy to process. Plastic has plasticity, that is, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. It can be processed into edge bands of their respective shapes by extrusion and other methods, such as T-shaped edge bands, H-shaped edge bands, D-shaped edge bands, V-shaped edge bands, I-shapes, and so on.
pvc furniture edge banding is of high quality and low price, and the price of plastic is far less than that of metal.
