Scaling down the size of BaLnF5nanocrystals (Ln = La, Gd, and Lu) with the Ln3+ size

Abstract

Monodispersed Yb³⁺(20%)/Er³⁺(2%)-doped BaLnF₅ (Ln = La, Gd, Lu) nanocrystals were synthesized by a thermal decomposition method. The study reveals that the size of the nanocrystals scales down with the Ln³⁺ size without affecting the phase and shape of the nanocrystals. This is supported by the microscopic and optical properties.
