The local symmetry of trivalent europium ion activated Li4Ca2B8O16 red-emitting phosphors with high color purity and excellent thermal stability

Exploring for red-emitting phosphor materials with supper property plays a key role in the development of white light-emitting diodes (WLEDs). Simultaneously, the crystal structure has a crucial effect on its luminescence properties. In this work, we synthesized a type of new red-emitting Li4Ca2B8O1...
