Advanced Functional Materials, EarlyView.Fluoroalkyl‐functionalized tin–oxo nanoclusters (N‐TOC6) enable robust pattern formation through ligand crosslinking under EUV exposure without thermal processing. Sn–F coordination mitigates the Lewis acidity of Sn centers, suppressing reactions with airborne molecules and improving post‐exposure pattern stability.

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties
Advanced Functional Materials, EarlyView.High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐
