Summary
Nickel-nickel co-doped transparent silicate glass-ceramic for broadband optical amplification and preparation method thereof, the composition of the glass-ceramic is as follows: SiO2 50-70 mol%; Ga2O3 15-30 mol%; Li2O 10-30 mol %; NiO 0.005 to 1 mol%; Yb2O3 0.005 to 2 mol%. The transparent glass ceramics prepared by the method of the invention can produce a stronger near-infrared communication band fluorescence than the single-doped nickel transparent silicate glass-ceramics under the 980 nm light source pumping test, and the test shows that the glass ceramics of the invention are close to The intensity of infrared fluorescence is about 8.5 times higher than that of single-doped nickel-plated glass. The fluorescence lifetime can be increased from 480 microseconds for single-doped nickel to 920 microseconds for co-doping. It is expected to be in broadband optical amplifiers, high-power lasers, and Applications such as tuning lasers have been applied.

AoshenÂ® Colorful Spandex fabric is elastane yarn which has pastel luster. Colorful spandex fabric that the color can keep long time, and will never fade.

Colorful Spandex

Key technical of Exclusive color paste and painting process for spandex were developed by utilizing environmental-friendly and nontoxic paints and dispersants. Meanwhile, by improving the equipment and technical process, realized the industrial production of colorful spandex. Colorful spandex can help to simplify dyeing procedures, reduce production cost, does good to energy conservation and emission reduction, health and environmental-protection.

Colorful Spandex

Advantage:

1. This series of product have pastel luster, pure color and colors can be customized.

2. The phenomenon of white exposed by spandex in dark fabrics can be eliminated thoroughly.

3. The color fastness reaches a high class and the color can keep long time, and never fade.

4. The rate of solvent residue is low and the pains used are environmental-friendly, nontoxic and healthful.

Application:

Widely applied to knitting, weaving and covering.
