Design and Practice on Comprehensive Teaching Experiment Based on X-ray Nano-Phosphors
In order to enhance the attractiveness of traditional experimental teaching and improve the comprehensive experimental skills and scientific research literacy of undergraduate students,the course team designed a research-based comprehensive experiment on the preparation and characterization of nano X-ray luminescent materials based on the principle of"one gender,one degree".The experiment used the uniform precipitation method combined with solid gas sulfurization technology to prepare nano Gd2O2S∶Tb3+luminescent materials.The structure,phase,morphology,and luminescent properties of the materials were characterized using X-ray diffraction,scanning electron microscopy,and luminescence spectroscopy.Through experimental learning and training,students'understanding of the synthesis and characterization methods of luminescent materials has been improved,their experimental operation ability has been strengthened,and their scientific research literacy and innovative thinking have been cultivated.
