| titleOfInvention | Additive Mn germanate solid solution red fluorescence powder and preparation method |
| abstract | The invention discloses additive Mn germanate solid solution red fluorescence powder, expression formula is K x Rb 2‑x Ge 4 O 9 :yMn 4+ , wherein 0≤x<2,0.005%≤y≤2.0%.The invention also discloses its preparation method, comprise the following steps：(1) raw material is weighed by expression formula；(2) pre-burning in an oxidizing atmosphere after raw mill is mixed；(3) sample after pre-burning is taken out, calcination in an oxidizing atmosphere after being ground；(4) sample after calcination is taken out, calcination in an oxidizing atmosphere again after being ground.The emission peak peak position of solid solution red fluorescence powder produced by the present invention, the excitation peak peak position of blue light region and fluorescence lifetime continuously adjustable, with broad ultraviolet and blue light absorption, ultraviolet or blue light is excited down with red fluorescence interval 600~750nm of covering, fluorescence lifetime is about 0.4~1.1 millisecond, is expected to be applied in fields such as white light LEDs, agriculture conversion films. |
