Effect of preparation conditions in sol-gel method on yellow phosphor with wide spectrum

Effect of preparation conditions in sol-gel method on yellow phosphor with wide spectrum

Among several methods to obtain white light in light emitting diodes (LEDs), mixing blue light with yellow light excited by blue light is the most effective and economical method. However, the quality of white light achieved by this method is poor, making it essential to develop high-quality yellow...
