Er3 + doped glass bead of borate glass – NEW!
Diameter about 12mm – weight 1.0 – 1.2g
Host: Zn-Te borate glass: Er3 + about 5 mol%
individually handmade in our lab. The proportion of tellurium dioxide in the glass results in a high refraction of light and high density.The glass beads are light pink in daylight and strongly pink in artificial light and have paramagnetic properties.
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.
