| Popis: | 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. |
