| titleOfInvention | Preparation method of yellow-green long afterglow fluorescent material and application of ammonium bicarbonate |
| abstract | The invention discloses a preparation method of a yellow-green long afterglow fluorescent material. The raw materials obtained according to the composition of the yellow-green long afterglow fluorescent material, the flux and ammonium bicarbonate are uniformly mixed to obtain a mixture; the mixture is calcined in a reducing atmosphere, and the calcined product is cooled to obtain a yellow-green long afterglow fluorescent material; the The composition of the yellow-green long afterglow fluorescent material is as follows: Sr 1‑x‑ y Al 2 O 4 :Eu 2+ x ,Dy 3+ y . The preparation method can improve the luminous intensity of the yellow-green long afterglow fluorescent material and reduce the afterglow decay speed. The invention also discloses the use of ammonium bicarbonate in increasing the luminous intensity of the yellow-green long afterglow fluorescent material or reducing the afterglow decay speed of the yellow-green long afterglow fluorescent material. |
