Study of sensitization process on mid-infrared uncooled PbSe photoconductive detectors leads to high detectivity
TL;DR: In this paper, photoluminescence and responsivity studies on polycrystalline PbSe photoconductive detectors were conducted and it was shown that oxygen only serves as an effective sensitization improver and it is iodine rather than oxygen that plays the key role in triggering the photo-response.
Journal ArticleDOI
Understanding sensitization behavior of lead selenide photoconductive detectors by charge separation model
TL;DR: In this article, a charge separation model was introduced to explain the mechanism of enhanced photoconductivity of polycrystalline lead salt photoconductors, and the results showed that this model could clarify the fabrication processes of such lead salt detectors that were not well understood and often considered mysterious for nearly a century.
Journal ArticleDOI

TL;DR: In this paper, a coaxial multiple-shelled TiO2 nanotube arrays were successfully synthesized on the transparent conductive oxide (TCO) substrates by using improved ZnO nanorod template assisted layer by layer absorption and reaction (LbL-AR) technique.
Journal ArticleDOI
Responsivity enhancement of mid-infrared PbSe detectors using CaF2 nano-structured antireflective coatings
TL;DR: In this article, the CaF2 nano-structures grown by thermal vapor deposition are presented and significant responsivity improvement (>200%) of mid-infrared PbSe detectors incorporating a 200-nm nano-structure was observed.
Journal ArticleDOI
Above-room-temperature optically pumped 4.12 μm midinfrared vertical-cavity surface-emitting lasers
TL;DR: In this article, an Optically pumped lead salt vertical-cavity surface-emitting laser (VCSEL) with a nine period PbSe/PbSrSe quantum well active region operating above room temperature in pulsed mode is reported.
