TL;DR: In this article, photolithography combined with colloidal self-assembly enables linear defects to be embedded inside an opal film, which can serve as templates for waveguides, and will allow colloidal PBG materials to be evaluated for integrated optics.

Kinetics versus Charge Separation: Improving the Activity of Stoichiometric and Non-Stoichiometric Hematite Photoanodes Using a Molecular Iridium Water Oxidation Catalyst
TL;DR: Oxygen-deficient iron oxide thin films, which have recently been shown to be highly active for photoelectrochemical water oxidation, were surface-functionalized with a monolayer of a molecular iridium water oxidation cocatalyst as discussed by the authors.
Absolute quantum yields in NaYF4:Er,Yb upconverters – synthesis temperature and power dependence
TL;DR: In this article, the authors investigated the temperature and power dependence of the emission quantum yield of NaYF4:Er,Yb upconverters and showed that the quantum yields may vary by almost three orders of magnitude.
