• Lasers&Photonics Congress: Quantum Dots and Topological Insulators

  The 18th Lasers&Photonics Congress has just kicked off in St. Petersburg; it includes several conferences, schools for young scientists and students, and an exhibition on laser and optoelectronic technologies. The main topics of the congress are: research into quantum dots and their practical application in lasers, a new concept of lasers based on topological insulators, as well as the possibilities offered by the European X-ray free-electron laser (XFEL), experiments on which began last autumn. These topics were discussed during the plenary presentations by the event’s main speakers. The congress is organized by ITMO University together with its partners.

• ITMO Begins Research on Carbon Nanodot Synthesis Methods

  The Russian Government has awarded Professor Andrey Rogach and ITMO University’s International Research and Education Center for Physics of Nanostructures with a “megagrant*” to facilitate the creation of the Laboratory “Light-emitting Carbon Quantum Nanostructures”. There, scientists will study new methods for synthesis of carbon nanodots, which are expected to find use in LEDs and for the purpose of biomedical sensing, i.e. the analysis of chemical substances in living tissue. These new eco-friendly structures will greatly fit into today’s popular “green” nanophotonics concept

• Optoelectronics On Quantum Dots: Review By ITMO Researchers

  Today, TV sets based on quantum dots are becoming a common thing, which means that one of the most interesting quantum technologies invented in the 1980s is being gradually introduced in our everyday life. Thanks to the development of colloid synthesis, quantum dots are now applied in many optoelectronic devices that can already compete with their regular counterparts - photovoltaic elements, LEDs, photon detectors. So, what are the key advantages of this technology, and are the new devices ready for mass production? What are the relevant issues that scientists will have to solve in the nearest future? A group of researchers from ITMO University answered these questions in a review on the new concepts and progress in studying quantum dots published in Journal of Materials Chemistry A - a title by the British Royal Society of Chemistry.

• Chemists Create Nanoparticles for Safe Imaging of Tumors

  Chemists from Russia and Switzerland created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attacks or strokes. The particles are made of hafnium oxide that can be used for intravenous injections, and doped with ions of rare earth metals. Scientists hope that their invention will become an alternative to the toxic quantum dots, and allow getting images of deep tissues without harming the human body. The study was published in Colloids and Surfaces B: Biointerfaces journal.
