Seientifie research achievements are integrated into the teaching of experiment, and a researchexperiment “ synthesis and characterization of upeonversion luminescent nanomaterials” is developed for theundergraduate students. Y,O, : Ybs* , Hos* upconversion luminescent nanomaterials are prepared using ahomogeneous precipitation method. The strueture , morphology , and luminescent properties of the materials arecharacterized by X-ray diflraction , transmission electron microscopy , and upeonversion emission spectroscopy.The influenee of particle size on the luminescent color is analyzed.The experiment includes research hotspotssuch as the preparation of nanomaterials and the study of upeonversion luminescence properties , involving theinter disciplinary fusion of the knowledge in physics, chemistry and materials.This experiment helps to stimulatestudents’ interest in the research of lumineseent materials and nanomaterials, deepen their understanding inmaterial synthesis methods and luminescent processes, not only expand their horizons and thinking, but alsostrengthen their comprehensive experimental skills.
