Abstract
A remote phosphor coating by using Sr3(Al,Si)(O, F)5:Ce3+ (SASF:Ce3+) on glass substrate was prepared by a simple and convenient screen printing method. The crystalline phase and the distribution of SASF:Ce3+ crystals in coating were investigated by XRD and SEM, respectively. The scattering light and absorption light properties of remote phosphor coating with different thicknesses were discussed through Lambert–Beer’s law. The relationship between luminous efficiency and absorption coefficient was demonstrated. White light emitting diode prototype fabricated with blue chip and the prepared patterned SASF:Ce3+ remote phosphor in this work showed excellent performances, opening a cost-effective process to generate planar white light.
