Quantum dots are tiny structures of semiconductor materials 1 million times smaller than a sand grain that can emit light. Their properties (emission wavelength) can be controlled by the choice of semiconductor composition and by adjusting their size. The use of Quantum Dots (QDot) in lasers technology started in the 90s. This is a relatively new area and, although only a few suppliers worldwide exist, they have very attractive properties for commercial gas sensing. Cascade Technologies designs and manufactures gas analysers based on advanced laser technology for a range of markets: environmental monitoring, gas process industries, food industries, pharmaceuticals. One of the commercial limitations of these systems is their manufacturing price (one of the main components being the price of the laser), the laser performance and the laser’s emitting wavelength availability. In this project, Cascade Technologies and Lancaster University will work together to design, build and test QDot lasers relevant to gas sensing applications. The access to new wavelengths in the mid-IR region would mean that Cascade would gain access to different markets. A reduction in price of the

量子点是半导体材料的微小结构，比沙粒小100万倍，可以发光。它们的性质（发射波长）可以通过选择半导体成分和调整它们的尺寸来控制。量子点（QDot）在激光技术中的应用始于90年代。这是一个相对较新的领域，尽管全球只有少数供应商存在，但它们对于商业气体传感具有非常有吸引力的特性。Cascade Technologies设计和制造基于先进激光技术的气体分析仪，适用于一系列市场：环境监测、气体加工行业、食品行业、制药行业。这些系统的商业限制之一是它们的制造价格（主要因素之一是激光器的价格）、激光器性能和激光器的发射波长可用性。在该项目中，Cascade Technologies和兰开斯特大学将共同设计、制造和测试与气体传感应用相关的QDot激光器。获得中红外区域的新波长意味着Cascade将进入不同的市场。价格的降低
