Description
Technical field
The invention belongs to fluorescent material technical field more particularly to a kind of carbon nitrogen powder yellow fluorescent material and preparation sides
Method.
Background technique
Currently, the prior art commonly used in the trade is such that
Fluorescent material is with metal (zinc, chromium) sulfide or rare earth oxide and trace active agent through calcining.
Colourless or shallow white is under ultraviolet light (200~400nm) irradiation, not according to metal in pigment and activator species, content
Together, the visible light (400~800nm) of various colors is showed.
Commercial white light-emitting diodes generallys use blue light diode excitation yellow fluorescent powder and forms white light, most common yellow
Fluorescent powder is that cerium-doped yttrium aluminum garnet Y3Al5O2:Ce3+ (" YAG:Ce ") containing heavy metal has bigger toxicity, in mining industry
Exploitation is smelted, in fluorescent powder production and transportation, there is bigger pollution to environment.Yttrium is non-renewable, and raw
