Featured Application The investigated materials have great potential for integrated
optoelectronic devices. The possibility to integrate them into the same material as optical …

ZnO nano-and microstructures doped with K were grown by the Vapor–Solid method. Wires
and needles are the main morphology observed, although some structures in the form of …

We demonstrate a simple optical based humidity sensor using a micro cavity. The micro
cavity consists of single mode fiber (SMF-28e, Corning) and a reflective mirror coated with …

The formation of optical cavities in Li-doped ZnO nanostructures was investigated. By means
of the vapor–solid method, long micro-and nanostructures with a hexagonal cross-section …
