LUMINESCENCE OF MANGANESE-ACTIVATED MAGNESIUM GERMANATE,

Abstract

The emission spectrum of Mg4GeO6:0.01 Mn has been found to depend on the temperature of preparation. The spectrum of the sample prepared at 1275C shows four narrow bands at 6200 Angstroms to 6600 Angstroms; the spectrum of the sample prepared at 1475 C consists of a broad band centered at 6150 Angstroms. X-ray diffraction patterns of the powders indicate the presence of an intermediate phase in the sample prepared at 127 C. It was concluded that the valence of the manganese activator is different in the two samples. (Author)
