Textbook in PDF format This book examines halide perovskites as semiconductors of interest for advanced photonics. Halide perovskites are highly important in innovative applications such as energy harvesting, sensors, radiation detectors, and optoelectronic devices. The book provides an in-depth experimental and theoretical analysis of recent results in photonic applications with a focus on excitonic properties, coherent and incoherent light emission, defects, doping, and perovskite metamaterials and metasurfaces. Key features A concentrated discussion of nanostructured halide perovskites Both experimental and theoretical results Up-to-date information on halide perovskites as an emerging class of materials of high research interest Halide Perovskites for Photonics is an excellent foundational work for researchers and professionals in photonics and the related fields of physics, chemistry, and materials science
