Abstract

A new series of CaY2–10xYb9xErxGe3O10 trigermanates (space group P21/c, Z=4) has been synthesized using an EDTA-assisted method. Under 980nm laser diode excitation, the samples exhibit intense upconversion luminescence corresponding to the characteristic transitions 2H9/2→4I15/2 (400–420nm), 2H11/2,4S3/2→4I15/2 (500–600nm) and 4F9/2→4I15/2 (625–725nm) in Er3+ ions. The CaY1.5Yb0.45Er0.05Ge3O10 phosphor can be used as a good temperature sensor with high absolute and relative sensitivities Sa(max)=0.0051 K−1 and Sr(max)=0.0109 K−1.
