Аннотация
A series of Gd11–x–yYbxEryGeP3O26 germanate phosphates differing in the ratio of the Yb3+ and Er3+ active ions have been synthesized, and their luminescence spectra have been measured. According to X-ray diffraction characterization results, all of the synthesized germanate phosphates are single-phase and have a triclinic structure (sp. gr. P1). We have measured upconversion luminescence spectra due to the Er3+2H11/2, 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 radiative transitions in the synthesized gadolinium ytterbium erbium germanate phosphates and determined the luminescence upconversion energy yield (Ben) in Gd11–x–yYbxEryGeP3O26. The effects of the concentrations and ratio of the dopants in the Gd11(GeO4)(PO4)3O10 germanate phosphate host on Ben and the ratio of the luminescence intensities in the red and green spectral regions (R/G) have been assessed.
