论文部分内容阅读
  Silicon-(oxy)nitrides have rich structures based on [SiN4] or [(Si,Al)(N,O)4] tetrahedra,which can accommodate various cations and form complicated solid-solutions.These structures can adjust 5d energy levels of rear-earth ions and luminescent features,which is currently adopted to develop novel silicon-(oxy)nitride phosphors for white LEDs.
