- •
Yb(20%):Er(0.5%):KY3F10 nanocrystals were synthesized by co-precipitation method.
- •
A time-resolved luminescence spectroscopy was used to characterize the upconversion luminescence.
- •
Luminescence effects on visible emission of Er3+ ions induced by thermal treatments were investigated.
- •
Strong cross-relaxations between Er3+ ions were observed to occur in as grown nanocrystals.
- •
Our study contributes for understanding the luminescence properties of RE3+-doped nanocrystals.
