Study on Co-precipitation Synthesis, Structure Characterization and Photoluminescent Properties of K2GeF6: Mn Phosphors

Abstract

: A research-based comprehensive experiment was introduced: co-precipitation synthesis, structure characterization and photoluminescent properties of K 2 GeF 6 :Mn phosphors. Chemical redox and co-precipitation method was employed to synthesize K 2 GeF 6 :Mn phosphors. By using XRD, SEM and PL spectra characterization techniques, the effects of Mn contents and reactive temperatures on the structure and properties of K 2 GeF 6 :Mn phosphors were studied. The red phosphors show great potential in LEDs applications. Through this experiment, students can master the basic laboratory skills; interpret the experimental principles with their basic theoretical knowledge, which will further enhance their scientific research ability and comprehensive application of knowledge.
