锰钛共掺杂碱土氟钪酸盐发光材料、制备方法及其应用
摘要：
一种锰钛共掺杂碱土氟钪酸盐发光材料，其化学式为MeSc2F8∶xMn4+,yTi4+，其中，x为0.01～0.05，y为0.01～0.08，Me选自镁元素，钙元素，锶元素和钡元素中至少一种。该锰钛共掺杂碱土氟钪酸盐发光材料制成的发光薄膜的电致发光光谱（EL）中，在650nm波长区都有很强的发光峰，能够应用于薄膜电致发光显示器中。本发明还提供该锰钛共掺杂碱土氟钪酸盐发光材料的制备方法及其应用。
摘要（英）：

The invention relates to a manganese/titanium-codoped alkaline earth fluoscandate luminescent material, a chemical formula of the luminescent material is MeSc2F8: xMn<4+>, yTi<4+>, wherein x is 0.01-0.05, y is 0.01-0.08, Me is selected from at least one of magnesium element, calcium element, strontium element and barium element. In an electroluminescent spectrum of a luminescent film prepared by the manganese/titanium-codoped alkaline earth fluoscandate luminescent material, a strong luminescence peak is generated at a 650nm wavelength zone, and the manganese/titanium-codoped alkaline earth fluoscandate luminescent material can be used in a thin-film electroluminescence display. The invention also provides a preparation method and an application of the manganese/titanium-codoped alkaline earth fluoscandate luminescent material.
