掺铕铝酸锶是一种著名的绿色荧光体，它在机械应力作用下可以发光，称为弹性发光。报道了一种改进的反胶束法制备掺铕铝酸锶纳米粒子。在反胶束中形成的前体的表面上涂覆聚合物基质。聚合物基质被认为通过在前体热处理时形成碳层来防止颗粒团聚。因此，在还原气氛下去除碳层并形成发光中心之后，获得发光纳米颗粒。本文对纳米发光材料的制备工艺和性能进行了讨论。
Europium-doped strontium aluminate is a famous green phosphor that can give luminescence under a mechanical stress that is named elastico-luminescence. This paper reports a modified reverse micelles process for preparing the europium-doped strontium aluminate nanoparticles. A polymeric matrix was coated on the surface of the precursor formed in the reverse micelles. The polymeric matrix is considered to prevent the particle agglomeration by forming a carbon layer while the precursor was heat-treated. Consequently, the luminescent nanoparticles were achieved after removing the carbon layer and forming the luminescent center under a reducing atmosphere. The processing and properties of the luminescent nanoparticles were discussed in this paper.
