这项工作研究了胶体，半导体硒化镉（CdSe）量子点的光谱测量。定制的显微镜已被用于光致发光光谱，并已收集图像，视频和样品的光谱，以研究基板，样品密度，均匀性和QD老化随时间的影响。该设置将用于检测单个到几个分子，通过荧光闪烁或QD闪烁显示。光谱中的差异将被记录为与样品的年龄、量子点的密度和样品的浓度有关。进一步的实验包括通过金纳米颗粒或纳米结构对QD光致发光的潜在等离子体增强。
This work investigates colloidal, semiconductor Cadmium Selenide (CdSe) QDs with optical spectroscopy measurements. A custom-built microscope has been used for photoluminescence spectroscopy and has collected images, videos, and spectra of samples to study the effects of substrates, sample density, uniformity, and QD aging with time. This set up will be used to detect single to a few molecules, shown by fluorescent intermittency, or QD blinking. Differences in the spectrum will be noted as related to the age of samples, the density of the quantum dots, and the concentration of samples. Further experiments include the potential plasmonic enhancement of QD photoluminescence by gold nanoparticles or nanostructures.
