Advanced Materials, EarlyView.Er3⁺/Mn2⁺ co‐doped ZnS/CaZnOS heterostructures are developed for remote temperature and force/sound sensing. The material exhibits UV/NIR photoluminescence, with energy transfer influencing color. Mechanoluminescence intensity is measured against applied power. Temperature‐dependent photoluminescence enabled luminescence thermometry.

How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, EarlyView.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
