Preparation and Characterization of Europium(III) Complexes with Cinnamic Acid by Microwave Process
A novel material synthesis technique, microwave process was investigated for the production of phosphor powders. In this study, we have developed a new method to product phosphor powders, and applied this process into two materials fabrication. EuDL3 where L is cinnamic acid (C6H5CH = CHCOOH, HL), D = 2, 9-dimethyl-1, 10-phenantroline (dmp), or 2, 2'-bipyridine (bipy) phosphor powders were successfully synthesized by microwave process. The process takes only 24 min to obtain two phosphor powders. The process takes only 24 min to obtain two phosphor powders. The resultant phosphor powders were investigated by TG-DTA, IR, luminescence spectroscopy, and scanning electron microscope (SEM). The results revealed that the two materials is significant different, compared to micrographs of scanning electron microscope (SEM).
