锰钛共掺杂氮锗酸盐的发光薄膜及其制备方法和电致发光器件
摘要：
本发明属于光电材料领域，其公开了一种锰钛共掺杂氮锗酸盐的发光薄膜及其制备方法和电致发光器件；该发光薄膜的其化学通式为:Me1-x-yGe2O2N2:xMn4+,yTi4+；其中，Me1-x-yGe2O2N2是基质，Mn4+和Ti4+分别是激活光离子和敏化离子，Mn4+为发光薄膜的发光中心，Me选自Mg，Ca，Sr或Ba元素，x的取值范围为0.01～0.05，y的取值范围为0.005～0.03。锰钛共掺杂氮锗酸盐的发光薄膜，其电致发光谱（EL）中，在646nm位置有很强的发光峰。
摘要（英）：

The invention belongs to the field of photoelectric materials, and discloses a manganese titanium co-doped nitrogen germanate light-emitting film and a preparation method thereof and an electroluminescent device; the light-emitting film has a chemical formula of Me1-x-yGe2O2N2:xMn<4 +>, yTi<4 +>; wherein Me1-x-yGe2O2N2 is a matrix, Mn<4 +> and Ti<4 +> are respectively activated light ions and sensitized ions, the Mn<4 +> is light-emitting centers of the light-emitting film, Me is selected from the group consisting of Mg, Ca, Sr or Ba element, the value range of x is 0.01-0.05, and the value range of y is 0.005-0.03. In the electroluminescence spectrum (EL) of the manganese titanium co-doped nitrogen germanate light-emitting film, strong light-emitting peaks show at 646 nm position.
