In order to prevent Zn2SiO4:Mn2+with short decay time for 3D plasma display panels (PDPs) from the deterioration of the luminescence efficiency caused by vacuum ultraviolet (VUV) irradiation, MgF2coated Zn2SiO4:Mn2+phosphor samples were prepared by a sol-gel process. The influence of the coating percentage on the photoluminescence properties was investigated.The results show that: MgF2coatings can improve the Zn2SiO4:Mn2+phosphor emission intensity, brightness as well as VUV irradiation stability. And the optimal coating percentage on the luminescent intensity is also achieved: under 147 excitation, the optimal MgF2coating mass ratio is 0.8%, with the best brightness of 11.5% and improved VUV irradiation stability, compared with the raw phosphor. |
