These vivid green glass pieces are made from praseodymium metaphosphate, a rare-earth phosphate glass with a remarkably high concentration of praseodymium ions. The intense coloration originates from characteristic Pr³⁺ electronic transitions, giving the glass its distinctive bright green appearance.
Each piece is carefully melted and formed to produce a bubble-free, optically homogeneous material with a smooth and shiny surface
Key Features
- Composition: Pr(PO₃)₃ (Praseodymium metaphosphate)
- Praseodymium content: ~25 mol% (as Pr³⁺)
- Appearance: Bright, transparent green
- Structure: Amorphous phosphate glass
- Form: Solid polished glass pieces
Applications
- Optical and spectroscopic demonstrations
- Rare-earth material collections
- Educational and research purposes
- Decorative scientific glass
This is not a doped glass, but a true rare-earth metaphosphate glass, where praseodymium is a major structural component. As a result, it exhibits significantly higher rare-earth content than conventional optical glasses.
Due to the phosphate glass nature, prolonged exposure to high humidity should be avoided for optimal long-term stability.
