 Nice Palladium 3+ doped glass bead NEW!  Art. Nr. 005047  
Nice Palladium 3+ doped glass bead NEW!
magnify Click to zoom!

Glass bead doped with Palladium (Pd3+) Ions

Material: BaP:0.4Pd3+

Size about 13mm - Weight ~ 1 - 1.2g

Nice glass bead. Each one handmade of phosphate glass in our lab.

Doping glasses with Palladium is a very complicated task and several attempts failed due to the extremely low solublity of Pd in any glass matrix. Finally I was able to successfully produce some Pd3+ containing glass samples. The max. concentration of Pd3+ is about 0.4 mol%. All attempts with higher amounts failed.

Black Phosphorus 10.0g sealed under Argon in ampoule

High pure black Phosphorus crystals produced by gas phase transport - The highly shiny and very stable crystals have a bluish black metallic luster. You get 8 - 10 crystal clusters from which single crystals can be isolated. By scotch tape method very thin '2D-Layers' can be obtained. These samples are perfecty suited for semiconductor experiments. 

For analysis data (XRD, Raman, TEM) please refer to selected science papers where our material has been used.
