| Abstract: | The red shift of the green emission band of ZnS:Cu, Br phosphors has been observed in (Zn,Cd)S:Cu,Br phosphors with different concentration of CdS.The green ACEL phosphors were made by general way. CdS was diffused into the green ACEL phosphors at temperature 600-700℃ for 1/2 hour-one hour. Five yellow ACEL phosphors have been obtained.The brightness of these five phosphors 706-2、 706-3、 706-4、 706-5 and 706-6、 are 16, 21.4, 18.5, 9.8, 2.5cd/m2 respectively, when a sinusoidal electric field 50Hz and 220V is applied. The concentration of CdS in these phospors are 0, 3, 10, 17, 23, mol% respectively.The lattice stucture of all ZnS and (Zn, Cd)S phosphors were determined by X-ray analysis. It show that hexagonal strucure is increased with the concentration of CdS being increased.Electroluminescent properties including bringhtness, emission spectra, deterioration and the dependent of frequency for the luminance have been studied also. |
