Abstract

Near-infrared luminescence in titanate-germanate glasses co-doped with Cr³⁺/Ln³⁺ (where Ln = Tm or Ho) have been investigated under different excitation wavelengths. Near-infrared emission spectra and their decays were analyzed for glass samples varying with TiO₂ content. Several emission bands in the 950–1570 nm and 1570–2200 nm spectral ranges are observed for glass samples excited directly at 600 nm (Cr³⁺), which correspond to characteristic transitions of Cr³⁺ and Ln³⁺ (Ln = Tm, Ho) ions. It suggests that the energy transfer processes Cr³⁺ → Tm³⁺ and Cr³⁺ → Ho³⁺ occur. It was also confirmed by the excitation spectra measurements. The experimental results indicate that titanate-germanate glasses co-doped with Cr³⁺/Ln³⁺ (Ln = Tm or Ho) are promising for near-infrared luminescence applications.

共掺杂Cr3+/Ln3+ （Ln=Tm或Ho）钛酸锗酸盐玻璃的近红外发光

研究了在不同激发波长下，共掺杂Cr3+/Ln3+ （Ln = Tm或Ho）的钛酸锗酸盐玻璃的近红外发光。对不同TiO2含量玻璃样品的近红外发射光谱及其衰减进行了分析。在600 nm （Cr3+）下直接激发的玻璃样品在950 ~ 1570 nm和1570 ~ 2200 nm光谱范围内观察到多个发射带，对应于Cr3+和Ln3+ (Ln = Tm, Ho)离子的特征跃迁。结果表明，相变过程中存在Cr3+→Tm3+和Cr3+→Ho3+的能量传递过程。激发光谱测量也证实了这一点。实验结果表明，共掺杂Cr3+/Ln3+ （Ln = Tm或Ho）的钛酸锗酸盐玻璃具有较好的近红外发光应用前景。

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
