Problems solved by technology

In order to make special silicon-based optical fibers doped with particles such as rare earth elements or metal elements, MCVD (modified chemical vapor deposition) technology is widely used, but the silicon-based glass prepared by this technology can only be limited to 100ppmW (Parts Per Million in Weight), which limits the development of silicon-based glass-based visible light upconversion materials

Embodiment Construction

[0035] The invention provides a green light tellurate glass doped with Yb ions and Tb ions, the composition of the green light tellurate glass is 65-90 mol% TeO 2 , 5~25mol% ZnO, 3~20mol% Na 2 O and additionally doped with 1-4wt% Yb 2 o 3 and 0.5-2wt% Tb 2 o 3 Prepared. Among them, sodium oxide can be obtained in various ways, such as adding Na 2 CO 3 , NaNO 3 . The way to obtain Yb is other forms of ytterbium oxide and other ways to obtain Yb ions, and the mass content is converted according to the mass ratio of Yb ions in the total. The way to obtain Tb is other forms of oxides and other ways to obtain Tb ions, and the mass content is converted according to the proportion of Tb ions in the total.

[0036] The composition of the above-mentioned Yb / Tb-doped green tellurite glass includes: 68-86mol% TeO 2 , 7-22mol% ZnO, 5-15mol% Na 2 O preparation and additional doping of 1.2-3.8wt% Yb 2 o3 and 0.6~1.8wt% Tb 2 o 3 Prepared.

[0037] The composition of the above-...

Description

technical field [0001] The invention belongs to the field of optics, and relates to a glass and a preparation method thereof, in particular to a Yb and Tb-doped green light tellurate glass and a preparation method thereof. Background technique [0002] Coherent visible light and near-ultraviolet radiation can have many very valuable applications, such as medical diagnosis and treatment, biological gene sequencing, underwater communication and rescue, red-green-blue (RGB) all-optical three-dimensional display, color laser projection, high Density data storage, high-resolution printing, advanced scientific instruments, etc. Taking three-dimensional display as an example, researchers use near-infrared lasers to emit visible light in solid liquids and gases to achieve display. Researchers have relied on a two-step upconversion process doped with rare earth ions, excited using crossed infrared lasers. After decades of efforts, research in this field has focused on upconversion ...
