摘要

Under 971 nm excitation, bright green and red emissions from Yb³⁺/Er³⁺ co-doped Ba5Gd8Zn4O21 phosphor can be observed, especially the intense red emission in highly doped samples. The experimental results indicate that Ba5Gd8Zn4O21:Yb³⁺, Er³⁺ emits stronger upconversion luminescence than NaYF4:Yb³⁺, Er³⁺ under a low excitation power, and a maximum upconversion power efficiency of 2.7% for Ba5Gd8Zn4O21:Yb³⁺, Er³⁺ was achieved. More significantly, to explain the red emission enhanced with the dopant concentration, this paper presents a possible cross-relaxation process and demonstrates it based on the rate equation description and temporal evolution. In view of the strong upconversion luminescence, colour tunable ability and stable chemical nature, Yb³⁺/Er³⁺ co-doped Ba5Gd8Zn4O₂₁ phosphor could be an excellent candidate for efficient upconversion luminescence generation.
