Description

technical field

[0001] The invention relates to a preparation method of a composite compound, in particular to a preparation method of a composite compound with specific specific surface area and dispersion index which can be used as a light-emitting material precursor. Background technique

[0002] The specific electronic structures of Eu, Tb, Dy, Gd, Ce, and Mn elements make it possible to obtain a variety of functional materials by adjusting the matrix material and synthesis conditions. Especially when used as luminescent material activator ions, the emission spectrum can cover a wide range from ultraviolet to near infrared. At the same time, because the corresponding luminescent material has the advantages of high luminous intensity and high color rendering, it has been used in lighting and display etc. The field has been widely used, and the corresponding TV and energy-saving lamps have become an indispensable part of people's daily life.

[0003] With the continuous d...
