WebAug 22, 2016 · Ions in 0.2 moles = 0.2 x 6.022 x 10 23 = 1.2044 x 10 23 ions. Charge on each ion = 3 x 1.602 x 10 -19 = 4.806 x 10 -19 coulombs. So, charge of 19g of PO 4 3- ions = 1.2044 x 10 23 x 4.806 x 10 -19 coulombs = 5.78 x 10 4 Coulombs . WebWith a Sm3+ ion concentration at x = 0.06, the luminescence intensity reached a maximum and then concentration quenching occurred. In addition, the effect of adding a charge compensator A(+) (A = Li, Na and K) on the luminescence properties of Ca3Sr3(PO4)(4):Sm3+ was investigated.
