Quantum Dots

This topic-in-depth addresses the characteristics and numerous applications of the semiconductor nanocrystals, quantum dots. First, Evident Technologies' Nanotechnology website provides a great summary about the properties of quantum dots (1 ). Users can learn about quantum dots' photoluminescence spectra, molecular coupling, quantum confinement, and their absorption spectra. The second website, created by Gunjan Mishra at the University of Nevada - Reno, is a downloadable slideshow illustrating the history, formation, and application of quantum dots (2). While created as part of a lecture series, this website provides students with a concise outline of the unique characteristics of the particles. Third, UCLA describes the combined research of chemists and engineers to use quantum dots as an inexpensive means of creating nanoscale circuitry for molecular computers of the future (3). Users can learn how the particles' photocatalytic properties make them a great candidate for improving the current method of creating interconnecting lines on silicon chips. Next, Stanislaus Wong at Stony Brook University presents his research in carbon nanotubes and semiconductor nanocrystals (4 ). After a short introduction about quantum dots, users can discover his group's efforts to understand these particles in order to implement them in the fields of chemistry and biology. The fifth site is a downloadable document by Victor Klimov at Los Alamos National Laboratory discussing the development of a new laser based on quantum dots (5 ). The site supplies a series of figures illustrating the nonradiative multiparticle auger recombinations in nanocrystal quantum dots, amplified spontaneous emissions, and more. Next, Nanotechweb compares new quantum discoveries in the 21st century to the ball-bearing inventions in the 20th century (6 ). Users can learn why scientists believe the particles can be utilized in medicine, security, and electronics. In an online article, Carnegie Mellon discusses how chemists are researching quantum dots to evaluate their effectiveness in treating diseases such as cancer (7). Users can discover how the scientists were able to produce quantum dots that fluoresced for an unprecedented eight months. The last site promotes the 2004 Quantum Dots Conference (8). Researchers can learn about the conference scope, the venue, invited speakers, and more.
