Creation of heavily La-doped SrTiO3 thermoelectric films achieved by freeze-dry pulsated orifice ejection method and laser powder bed fusion

Smart Materials in Manufacturing
Achieving both fine grain sizes and high doping levels simultaneously holds great promise for improving the dimensionless figure of merit (zT) of oxide thermoelectric materials; however, this remains a global challenge.

High Efficiency NIR Luminescence Beyond 900 nm Through Promoting Cr3+ Pair Generation in Sr3Zr2O7 Layered Perovskite

Laser &Photonics Reviews, EarlyView.
A Cr3+/La3+ codoped Sr3Zr2O7 NIR phosphor showing luminescence at ∼960 nm with high IQE/EQE (92.4%/57.5%) and good thermal stability was developed. La3+ stabilizes Cr3+ and induces Cr3+ pairs, enabling efficient blue‐to‐NIR conversion for underwater wireless optical communication.
