Visible to near-infrared luminescence properties of Nd{sup 3+}-doped La{sub 2}BaZnO{sub 5} phosphor
La{sub 2}BaZnO{sub 5}:Nd{sup 3+} phosphors are synthesized by a conventional high temperature solid state reaction method, and its crystal structure and luminescence properties are investigated. Photoluminescence bands peaking at ∼496, 540, 630, 670, 905, 1070, and 1350 nm of La{sub 2}BaZnO{sub 5}:Nd{sup 3+} phosphors are observed at room temperature due to f–f transition of Nd{sup 3+} ion. The optimum Nd{sup 3+} doped concentration is ∼0.03. Lifetimes of La{sub 1.97}BaZnO{sub 5}:0.03Nd{sup 3+} phosphor with 496 and 1070 nm monitoring wavelengths are ∼280 and 250 µs, respectively. The luminescence mechanism is explained by using simplified energy lever diagram of Nd{sup 3+} ion. La{sub 2}BaZnO{sub 5}:Nd{sup 3+} material can be applied to powerful solid-state lasers as high efficient light sources. - Graphical abstract: PL spectra of La{sub 2}BaZnO{sub 5}:Nd{sup 3+} phosphor in the visible and near-infrared regions and their corresponding to PLE at room temperature. - Highlights: • La{sub 2}BaZnO{sub 5}:Nd{sup 3+} phosphor is synthesized. • PL spectrum is observed in the visible region. • PL spectrum is observed in the near-infrared region.
