Evaluation of red CdTe and near infrared CdHgTe quantum dots by fluorescent imaging. Journal of nanoscience and nanotechnology, 2008, Volume: 8, Issue:3 Non-invasive fluorescent imaging of preclinical animal models in vivo is a rapidly developing field with new emerging technologies and techniques. Quantum dot (QD) fluorescent probes with longer emission wavelengths in red and near infrared (NIR) emission ranges are more amenable to deep-tissue imaging, because both scattering and autofluorescence are reduced as wavelengths are increased. We have designed and synthesized red CdTe and NIR CdHgTe QDs for fluorescent imaging. We demonstrated fluorescent imaging by using CdTe and CdHgTe QDs as fluorescent probes both in vitro and in vivo. Both CdTe and CdHgTe QDs provided sensitive detection over background autofluorescence in tissue biopsies and live mice, making them attractive probes for in vivo imaging extending into deep tissues or whole animals. The studies suggest a basis of using QD-antibody conjugates to detect membrane antigens.

[Defect analysis in mercury cadmium telluride by Raman scattering]. Guang pu xue yu guang pu fen xi = Guang pu, 2001, Volume: 21, Issue:4 Telluride precipitates in HgCdTe(MCT) and Raman scattering peaks of Hg vacancies are reported. We also analyze the relationship between the crystal surface perfection of MCT and its second-order scattering peaks. Intense bands at 125 and 145 cm-1 confirm them to be precipitates, and there is 2 cm-1 shift to high frequency in comparison with intense bands of normal trigonal Te. This shows the compressive stress exists around Te precipitates. The weak Raman peak at 108 cm-1 arise from Hg vacancies. This peak is only found in p-type MCT and MCT including p-n junction, and is not found in n-type MCT. The intensity of the second-order scattering peaks in MCT is very sensitive to its crystal surface perfect. To good surface perfect, these peaks are very distinct, and to poor surface perfect, they are not distinct. The intensity measurement of 2LO(T) mode in the second-order scattering peaks can provide useful information for surface analysis in crystal preparation process.
