Journal ArticleDOI
Random laser action in semiconductor powder
TL;DR: In this paper, the first observation of random laser action with coherent feedback in semiconductor powder was reported and the dependence of the lasing threshold intensity on the excitation volume agrees with the random laser theory.
Journal ArticleDOI
A nanotube-based field-emission flat panel display
TL;DR: In this paper, a matrix addressable diode flat panel display has been fabricated using a carbon nanotube-epoxy composite as the electron emission source and field-emission uniformity has been confirmed by measuring the I-V curves of pixels across the panel.
Journal ArticleDOI
Spatial confinement of laser light in active random media

TL;DR: The experimental data suggest that coherent amplification of the scattered light enhances the interference effect and helps the spatial confinement of laser light in micrometer-sized random media.
Journal ArticleDOI
Microlaser made of disordered media
TL;DR: The physical mechanism of optical confinement is based on Anderson localization of light in micrometer-sized random media, which occurs around 380 nm at room temperature under optical pumping.
Journal ArticleDOI
Self-assembled 3D photonic crystals from ZnO colloidal spheres
TL;DR: In this paper, a method for the controlled synthesis of monodisperse ZnO colloidal spheres is presented, where the spheres are self-assembled into fcc periodic arrays and optical measurements, including reflection-mode optical microscopy and transmission and single-domain reflection spectroscopy, reveal that the periodic arrays exhibit a photonic band gap in the (1 − 1 − 1 1) direction of the fcc lattice.
