文摘
- •
Calcium fluoride (CaF2) powders were prepared by combustion synthesis.
- •
Rare-earth ions doped in this material were found in interstitial sites.
- •
Cooperative up-conversion was observed in Tb3+:Yb3+:CaF2 powder.
- •
Energy transfer between Tb3+ and pairs of Yb3+ was analyzed using rate equations.
