Description
Nice Copper + doped Phosphate glass bead NEW!
Size about 13mm – Weight ~ 1 . 1.4 grams – Host: Sr Phosphate glass.
Nice glass beads. Each one handmade of phosphate glass in our lab.
Copper+ doped Phosphate glass shows strong luminescence under UV light.
Under reducing conditions Cu+ Ions can be kept in the glass. They show a strong pale yellow luminescence under 365nm UV light. The picture beneath shows the same beads under daylight. The slight green blue color comes from traces of Cu2+ Ions.
Beautiful optical glass beads doped with metal ions.
Elaborately and individually manufactured by us in the laboratory from highly pure reagents.
Gorgeous beads showing the typical colors of different metal ions in different oxidation states.
They can be used for save demonstration of different colors of the metal compounds or just for collecting.
