Article
A way of analyzing the spatial distribution of a solution on a substrate with a developed nanostructured surface (a metallized metasurface) is proposed. The technique is based on epi-luminescence microscopy and can be used to calculate the gain of the SERS signal on a surface with a complex highly-developed structure, where standard ways of estimat...

Colloidal semiconductor nanocrystals (quantum dots, QD) manifest specific temperature dependent luminescence. Here we analyse temperature dependences of CdSe QD luminescence spectrum shift for different composites: polymers, glasses, crystals. The analysis was performed in the terms of electron-phonon coupling, that allows to find and compare the p...

The influence of the concentration and the laser excitation wavelength on the width and luminescence spectrum maximum of CdSe/CdS /ZnS quantum dots in the toluene solution and doped on the glass plate was studied. It was shown that the wavelength of the exciting laser does not affect the width and peak center of the luminescence spectrum of the sam...
Article
The possibility of detecting signals of a two-pulse incoherent photon echo in a thin layer of double-coated semiconductor colloidal quantum dots spread on the surface of a glass substrate at T = 10 K is demonstrated. Possible mechanisms of ultrafast optical dephasing detected at the given temperature are discussed.

A simple and effective technique for fabricating homogeneous films of colloidal quantum dots is developed. Incoherent photon echo signals in the prepared thin films of quantum dots are detected and studied in a wide range of cryogenic temperatures (from 4.5 to 50 K). The temperature dependence of the inverse optical dephasing time is constructed an...
Article
A simple and effective technique for depositing thin films of semiconductor colloidal quantum dots (QD) on glass substrates is developed. Samples with CdSe/CdS/ZnS quantum dots are fabricated and investigated via luminescence microspectroscopy. Four-wave mixing signals are recorded at room temperature in a solution and in a thin film of quantum dot...

HBSM’2018 is organized by the Institute of Spectroscopy of the Russian Academy of Sciences (Troitsk, Moscow) in collaboration with the Moscow State Pedagogical University. The conference venue will be in the heart of the ancient Russian city of Suzdal, known as one of the best places that illustratively and vividly tell about the centuries of eventful and dramatic history of this land and its peoples. Laser selective spectroscopy has a special meaning for Russia. In 1952 the staff of the Department of Theoretical Physics of the Moscow State Pedagogical Institute under the direction of Prof. Eduard Shpol’sky was the first to observe the emergence of quasi-linear spectra of complex organic compounds in specially selected solvents at low cryogenic temperatures known as Shpolskii matrices. In 1972, a former student of Shpol’sky, Prof. Roman Personov and his colleagues at the Institute of Spectroscopy of the USSR Academy of Sciences have successfully performed a selective laser excitation of luminescence of organic molecules. Then, in 1974, researchers from Personov’s group and their colleagues from the Institute of Physics in Tartu, Estonia (USSR) conducted fundamental experiments on the persistent spectral hole burning. This work has formed the basis of laser site-selective spectroscopy of molecules, which has reached its culmination in single-molecule spectroscopy. HBSM was started in 1987 in Tallin, Estonia (USSR) as “All-Union Symposium on Modern Methods of Laser Spectroscopy of Molecules in Low-Temperature Media”. The next meetings were “Persistent Spectral Hole Burning: Science and Applications” in Monterey (California, USA, 1991) and “Spectral Hole Burning and Luminescence Line Narrowing: Science and Applications” in Ascona (Switzerland, 1992). The following meetings were organized as “International conferences on Hole-Burning and Related Spectroscopies (HBRS): Science and Applications” in Tokyo (Japan, 1994), Brainerd (Minnesota, USA, 1996) and Hourtin (France, 1999). In 2001, the Conference received its current name “Hole Burning, Single Molecule, and Related Spectroscopies (HBSM): Science and Applications”. The HBSM meetings were held in Taipei (Taiwan, 2001), Bozeman (Montana, USA, 2003), Aussois (France, 2006), Palm Cove (Australia, 2009), Tübingen (Germany, 2012) and Tartu (Estonia, 2015). This conference series has been exceptionally successful in bringing together participants from the leading research teams around the world to discuss the latest developments in the fundamental science and the applications of site-selective and single-molecule spectroscopy and related topics. We are looking forward to seeing you in Suzdal!
