Experimental Teaching Design of "Material Preparation Technology" Based on the Integration of Science and Education:Preparation of New Light-Emitting Materials for Lighting
The comprehensive experimental teaching of research-based material preparation technology was carried out to combine the scientific research project and experimental teaching organically,to strengthen the effect of talent cultivation by integrating and co-progressing,which helps to promote the process of education and teaching reform.The CaMoO4:Dy3+phosphor was prepared by microwave radiation method,the physical structure and surface morphology of the samples were tested by X-ray diffractometer (XRD)and SEM,the contained elements and their distribution were analyzed by mapping,and the luminescence performance of the CaMoO4:Dy3+phosphor was investigated by fluorescence spectrometer (PL).The results show that the CaMoO4:Dy3+phosphor can be prepared under the microwave power of 560 W pyrolysis for 30 min,and the luminescence performance is optimal when the Dy3+concentration is 3%.This experiment is dedicated to integrating the cutting-edge scientific knowledge and rigorous scientific research methods into undergraduate laboratory teaching,aiming to enhance students'practical ability and promote the cultivation and development of students'scientific research thinking,which in turn stimulates their innovative potential and creativity.
