Absorption electron spectra intensities of luminophores based on neodymium doped gallium, aluminium and zinc halogenides

It is shown that in aqueous solutions of neodymium chlorides the strength of 4I9/2-2,4G1/2,5/2 transition oscillators is within (9-10.5)·10-6. Coordination polyhedron is a trigonal prism. In SOCl2 and POCl3 base luminophores the strength of the band oscillators increases up to ∼24·10-6 at the expense of complication of internal coordination sphere. The symmetry of the coordination polyhedron decreases
