Key technologies and core materials of OLED

Born for the future, OLED leads the innovation of terminal ID OLED was first discovered in the lab by chinese-american professor deng qingyun. The principle is to make a current pass through special organic luminescent materials, and under the action of an electric field, stimulate the organic materials to make them glow. It’s a process that converts electrical energy into light energy. OLED is the basic structure of the layer of organic material to clamp on indium tin oxide (ITO) as [...]

New method for processing nanomaterials

Engineers at Rutgers University and Oregon State University are developing a new approach to nanomaterials that makes it possible to manufacture flexible thin-film devices from touchscreens to window coatings faster and cheaper. This method, known as “strong pulsed light sintering,” fuses nanomaterials in seconds with high energy rays that are nearly 7,000 times larger than lasers. Existing pulsed light fusion methods incorporate silver nanospheres into a conductive structure using a temperature of approximately 250 degrees Celsius (482 degrees Fahrenheit). But the [...]

Agglomeration and dispersion of nano powders

At present, all kinds of nanometer powders can be easily prepared, but the agglomeration of nanometer powders seriously hinders the application of nanometer powders and the preparation of nanometer materials. For nanomaterials with self-assembled structure, the designed structure cannot be obtained due to the agglomeration problem. For nanocrystalline materials, the agglomeration will cause the abnormal growth of particles and lead to the degradation of properties. For the occasions where nanometer luminescence and nanometer catalysis are used directly, the agglomeration [...]

Physical preparation of nano powders

Nano powders, also known as nanoparticles, generally refer to ultrafine particles between 1 and 100nm in size. Some people call them ultrafine particles. It is larger than a cluster of atoms and smaller than ordinary particles. In terms of its size, assuming that each atom is one angstrom in size, it contains between 1000 and 1 billion atoms. It’s smaller than a normal living cell, about the size of a virus. Nanoparticles are spherical, plate-like, rod-shaped, angular, spongy and [...]
