Broad spectral response photodetector based on individual tin-doped CdS nanowire

AIP Advances, 2014
High purity and tin-doped 1D CdS micro/nano-structures were synthesized by a convenient thermal evaporation method. SEM, EDS, XRD and TEM were used to examine the morphology, composition, phase structure and crystallinity of as-prepared samples.

Integration of glass microspheres and planar waveguides for microsphere lasers

, 2008
Microsphere resonators with sizes in the micrometer range are reported to support very high Q’s of more than 109 for a fused silica microsphere. This high Q value represents many promising characteristics such as low cavity loss, long cavity life time ...

Investigation of the Mode Structures of Multiphoton Induced Ultraviolet Laser in a ZnO Microrod

Journal of Nanotechnology, 2017
Hexagonal wurtzite structural ZnO microrods were fabricated by vapor-phase transport method. Under the excitation of a pulse laser with 1200 nm wavelength, the multiphoton induced ultraviolet (UV) laser was observed in a microrod.
