【Abstract】 Based on the concept of cultivating application and innovative talents, a research-type experiment of preparation of silicate-based rare earth luminescent materials was designed. In this experiment, the students should acquire frontier knowledge of rare earth luminescent materials, practice high temperature solid phase synthesis operation, analyze X-ray diffraction and fluorescence spectrum data, and fabricate white light emitting diodes(w-LEDs) devices. The project is beneficial for college students to consolidate their professional knowledge of inorganic chemistry, preliminary study the contents of crystallography and structural chemistry, deeply understand the luminescence mechanism of inorganic rare earth materials, learn how to draw scientific illustrations using Origin and write scientific papers. Meanwhile, it is meaningful for cultivating students’ innovative thinking and research ability. Moreover, through learning and practicing the high temperature solid phase synthesis operations and w-LEDs device assembly, the students can improve their experimental operation skills and application consciousness.更多还原
