dc.description.abstract |
In this paper a novel method for synthesis of LaInO₃:Er³⁺ is reported and upconversion luminescence properties of the synthesized material at different temperatures (9–300 K) are studied. The samples were prepared by co-precipitation and subsequent heat treatment of lanthanum, indium and erbium hydroxides. It is shown that the excitation at 980 nm leads to a strong green upconversion luminescence in the material. At the concentrations above 0.1 mol. % of Er³⁺ the energy transfer upconversion mechanism of the luminescence becomes evident. Further increase of Er³⁺ content in the material leads to higher red-to-green upconversion luminescence intensity ratio. The mechanisms responsible for the observed variation are discussed. |
