Europium 2+ Aluminum Strontium Phosphate Glass Bead

Exhibits a striking broadband lilac-blue fluorescence under UV light.
Dimensions: Approximately 12 mm in diameter.
Weight: Ranges from 1 to 1.4 g.
Color: Colorless transparent

This experimental glass is available in limited quantities.

The lilac-blue fluorescence is believed to result from energy transfer between Eu²⁺ and Al, though this hypothesis requires further investigation.

High Dysprosium Content Glass

Dysprosium Potassium Phosphate glass, containing over 17 mol% Dy2O3, has a distinctive pale lemon-yellow color. This glass is not only aesthetically pleasing but also exhibits strong paramagnetic properties, allowing it to lift a stack of neodymium magnets. While its yellow green fluorescence is slightly weaker compared to glasses with lower Dysprosium concentrations, it remains notably impressive.
