文摘
- •
A novel route to synthesize octahedral Y2O3:Eu3+ submicron crystals is developed.
- •
The synthetic process and growth mechanism of octahedral Y2O3:Eu3+ are discussed.
- •
The in situ formed salt is critical for octahedral formation during calcination.
- •
The octahedral Y2O3:Eu3+ exhibit enhanced photoluminescence than the spherical ones.
- •
The approach is addictive-free, high-yielding, eco-friendly and scalable.
