Application of high-purity alumina in luminescent materials

High purity aluminum oxide powder is a white powder with moderate high-temperature shrinkage, good sintering performance, high conversion rate, and low sodium content. It has been widely used in many fields. Today, Yangzhou Zhongtianli, a high-purity alumina manufacturer, will talk about the application of high-purity alumina in the field of luminescent materials.

1. High purity alumina is an important luminescent material for preparing tricolor aluminate series phosphors and long afterglow phosphors for LED lighting. Because the efficiency of a fluorescent lamp made of three primary colors of fluorescent powder is twice that of a halogen powder fluorescent lamp, a 20 watt fluorescent lamp can be as bright as a 40 watt fluorescent lamp, so it is called an energy-saving lamp.

2. The implementation of LED lighting is mainly achieved through the combination of LED chips and luminescent materials. High purity alumina has a decisive impact on the luminous efficiency, color rendering, and service life of LED devices. In recent years, significant progress has been made in the research of yellow, red, and green luminescent materials of silicate, nitride, and nitrogen oxide series used for LED chip excitation. Among them, garnet aluminate fluorescent powder has irreplaceable effects and application prospects due to its high light efficiency, excellent structure, and good chemical stability.

The above is the application of high-purity alumina in luminescent materials. Through these descriptions, I believe everyone has an increasing understanding of this material, and I hope these contents can bring some help to everyone.
