This cover illustrates the creation of robust, full-color perovskite nanocrystal composites stabilized by 2D ZrH P O nanosheets and embedded in a chiral polymer matrix. The hybrid architecture enhances photoluminescence efficiency and long-term stability while enabling strong dual-phase circularly polarized luminescence for next-generation chiroptoelectronic applications.

Compound Semiconductor Week (CSW) provides a broad overview of all aspects of compound semiconductors from basics to application. After a few years of colocation of International Symposium of Compound Semconductors (ISCS) and International Conference of Indium Phosphide and Related Materials (IPRM), CSW has become a joint venue for these two conferences.

Abstract Optical gain enhancement of two-dimensional CsPbBr3 nanosheets was studied when the amplified spontaneous emission is guided by a patterned structure of polyurethane-acrylate. Given the uncertainties and pitfalls in retrieving a gain coefficient from the variable stripe length method, a gain contour was obtained in the plane of spectrum energy (ℏω) and stripe length (x), whereby an average gain was obtained, and gain saturation was analysed.
