Rhodonite - PL spectra
Rhodonite:
- Red rhodonite – 3.28 ct - Unknown locality
- Red rhodonite – 0.94 ct – Conselheiro Lafaiete, Minas Gerais, Brazil
- 470 nm: ?
- 612 nm: Mn2+
- Excitation at 370 nm produces the two emissions at 470 and 612 nm as well.
Extremely weak photoluminescence, requires at least an integration time of 2.5s despite the power of the excitation souce.
No photoluminescence with the following sources: 254 and 405 nm.
