摘要:
A luminescent substance contains silicon and nitrogen as major components and has an amorphous structure. The silicon content of the luminescent substance is greater than the stoichiometric silicon content of Si3N4, and the luminous intensity of the luminescent substance has a maximum at approximately 2.2 eV. The luminescent substance has a high luminous efficiency and a short luminous decay lifetime. A light-emitting device includes this luminescent substance and a substrate. The luminescent substance can be readily formed on the substrate by a chemical vapor deposition process.
