文摘
- •
Novel NaYbF4:Nd3+@NaYF4:Yb3+ core-shell nanoparticles were synthesized.
- •
The maximum 45-fold enhancement of total emission intensity is realized.
- •
The nanoparticles show tunable green-white-yellow multicolor emissions.
- •
A maximum sensitivity of 0.0018 K−1 is obtained at 400 K for a temperature sensor.
