Properties of luminescent material for luminous fiber

The excitation spectra,emission spectra,and afterglow property of luminescent materials were measured by fluorescence spectrometer and afterglow tester.According to the luminous fibers requirements for luminescent materials,the particle size,spectral and afterglow properties of luminescent materials were studied.The results showed that the phosphor with particle size of 7-8 μm had better afterglow performance,and was consistent with the requirements of the luminous fiber.It was the first choice for luminous fibers.The change of Eu2 + and Dy3 + content did not lead to blue shift or red shift,but had an effect on the afterglow property of luminescent materials.The influences of H3BO3 content and sintering temperature on the luminescence properties were not independent.They have certain relevance with each other.
