Li-Based Nanoprobes with Boosted Photoluminescence for Temperature Visualization in NIR Imaging-Guided Drug Release

Lanthanide-doped fluoride nanocrystals have emerged as promising tools in biomedicine, yet their applications are still limited by their low luminescence efficiency. Herein, we developed highly efficient lithium-based core-shell-shell (CSS) nanoprobes (NPs) featuring a rhombic active domain and a spherical inert protective shell. By introducing Yb
