Effect of the Ratio of Na, K and Li on the PL Performance, Color and Composition of UCr4C4 Phosphor

This study uses an electrospinning process to produce UCr4C4 structured fluorescent fibers made of Na, K, Li and Eu. In this study, we will conduct SEM characterization of the fluorescent fiber, use a photoluminescence spectrometer to analyze the excitation and emission spectra of the fluorescent fiber, and the color change of the fluorescent fiber by changing the ratio of Na and Li. Finally, the composition ratio of the precursor solution in the electro spinning process was measured using a thermogravimetric loss analyzer.
