Abstract

With the development of LED technique

red-

(

=Ca

Ba) phosphors gradually become an important kind of three-primary-color phosphors. With the increasing of the patent applying amount

the broad application prospects of

phosphors have received great attention at home and abroad. To understand the application status of

phosphors comprehensively and promote the development of research and technique ultimately

this paper firstly reviews the patent applying amount over the years

important applicants and technical evolution of basic patents on preparing the phosphors. The synthesis methods are classified and compared. The creative points are concluded. The paper may be helpful for those persons in the field to acquire recently technical development on related industries

develop and protect valid patents.
