:0.05Eu phosphors were synthesized by high temperature solid phase method
and the phosphor phase
excitation and emission spectra
particle size distribution
surface morphology were investigated with the help of X-ray diffraction
spectrometer
granulometer and scanning electron microscopy. The influence of crucible lid-covering technology on the performance of the product was analyzed. The results indicate that the luminous intensity of the samples increases with the increasing of the crucible close degree. Crucible with lid is of benefit to the product for high purity Sr

phase. The particle size of the sample with crucible lid-covering is larger
but the size distribution is uniform.
