So luminous [...]

Rare earth luminescent materials new fulcrum

White LED light source is a green energy-saving light source. At present, it mainly USES the combination of InGaN ultra-bright blue chip and rare earth yellow and red phosphors with high light conversion efficiency to produce composite white light. It is regarded as the synonym of advanced technology and green lighting, and will become the leading role in the future lighting and display market. As we all know, the development of LED industry cannot be separated from rare earth [...]

From the aristocracy to the common people – new captain afterglow luminous materials

Long Persistent Luminescence (LPL) material is also known as luminescent Luminescence material, commonly known as luminous powder or Long afterglow powder. Its luminescence principle is photoluminescence, that is, when excited by the light source, the excitation energy is stored in the excited state. When the excitation stops, the energy is slowly released in the form of light. In 1996, Matsuzawa et al. published a strontium aluminate (SrAl2O4) system doped with europium (Eu) and dysprosium (Dy), with a decay time [...]
