Photon Transport in Disordered Photonic Crystals
, 2015 One of the daunting challenges in wave physics is to accurately control the flow of light at the subwavelength scale. By patterning the optical medium one can design anisotropic artificial medium, this engineering method is commonly known as photonic crystals or metamaterials.

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction
Advanced Functional Materials, EarlyView.X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.

Advanced Functional Materials, EarlyView.Four kinds of magnetite type NIR‐ML materials are synthesized by high‐temperature solid‐state reaction method. The continuous spectral tuning from a sharp R line (698 nm) to a broadband range (650–1000 nm) is realized based on composite engineering, concentration engineering, and lattice engineering strategies.
