Less than 2% interference was caused by iron, cobalt, manganese(II), phosphate, molybdate, acetate, fluoride, sulfate, and chloride. The following ions were tolerated in the indicated amounts : nickel, 50 mg ; vanadate, 50 rng ; bromide, 50 "16 ; aluminum, 40 rng; lead, 35 mg; zirconium, 5 mg; iodid
The polarized luminescence spectrum of single crystals of Zn3Eu2(N0,)12.24Hz0, measured at 77 K under laser-selective excitation, is presented. The spectra are interpreted by using Cp, symmetry, and are afterwards related to the crystallographic determined C, model at the site of the hexanitrate. Th
