Eu(2+), Dy(3+) and Tb(3+) co-doped strontium aluminate phosphor with high brightness and long afterglow was synthesized by a combustion method, using urea as a reducer. The properties of SrAl(2)O(4):Eu(2+),Dy(3+),Tb(3+) phosphor with a series of initiating combustion temperatures, urea concentration
Calcium aluminate phosphor co-doped Eu 2+ + + + , Dy 3+ + + + , Nd 3+ + + + is prepared by the combustion method. We study systemically the influences of the quantity of mixed Dy 3+ + + + ion, the quantity of flux H 3 BO 3 , the differences in dispersing methods between magnetic stirring and ultraso
Through the carbonization of 3CaO.A1203.6H20, the phase 3CaO.Al203.11H20 is formed first, nevertheless in the following period it decomposes into AI(OH) 3 and vaterite, which later is transformed into calcite. The degree of decomposition of C3AH 6 increases with time of reaction, concentration of CO
