摘要：
Room-temperature visible lasing in CdSe semiconductor nanotube arrays embedded in anodic aluminum oxide template has been demonstrated. The cylindrical nanocavities of anodic aluminum oxide template form laser resonators, and the laser oscillation was achieved through whispering gallery mode gain from the interior semiconductor nanotubes. The linearly polarized stimulated emission, the one dimensionality, and the chemical accessibility to nanotubes render them significant potential for serving as various applications in optoelectronic devices.
