1¡¢Scheelite structure materials have been widely used as a phosphor host. 2.For the purpose of comparison, the coating sol was evaporated in an 80¡ãCwater bath to form gel, which was annealed in a similar process to produce the pure NaGd0.95Eu0.05WO42 powder phosphor. 3.Excitation into CTB of WO42 at 249 nm yields the characteristic emission of Eu3+£¬which not only contain the characteristic emission from the lowest excited 5D0 but also those from higher levels £¨5D1, 5D2£© of Eu3+ with a very weak intensity. |
