文摘
- •
Al2O3–Yb3Al5O12 eutectic rods were grown with the laser floating zone method.
- •
Microstructure could be controlled by the solidification rate.
- •
Thermal emission up to 1500 °C was measured in the eutectic rods.
- •
High selective emission from Yb3+ ions was observed at 1 μm.
- •
The matched Yb3+ emission with the Si active region can improve the TPV conversion.
