Yb 3+ and Tm 3+ concentration-dependent structural and optical properties of hexagonal NaGdF 4 nanocrystals
TL;DR: In this paper, a detailed investigation of the influence of Yb3+ and Tm3+ ions concentration on the structural and optical properties of NaGdF4 nanocrystals was performed.
Journal ArticleDOI
Optical Properties of Active Regions in Terahertz Quantum Cascade Lasers
M. Dyksik,Marcin Motyka,W. Rudno-Rudziński,Grzegorz Sęk,Jan Misiewicz,Damian Pucicki,K. Kosiel,I. Sankowska,J. Kubacka-Traczyk,M. Bugajski +9 more
TL;DR: In this paper, three independent absorption-like optical spectroscopy techniques were employed in order to study the band structure of the minibands formed within the conduction band, and the obtained energy separation between the second and third confined electron levels, expected to be predominantly contributing to the lasing, was found to be ~9meV.
Journal ArticleDOI
Investigation of dielectric cap induced intermixing of InxGa1−xAsyP1−y/InP quantum well laser structures by photoreflectance and photoluminescence
Robert Kudrawiec,Grzegorz Sęk,W. Rudno-Rudziński,Jan Misiewicz,Jacek Wojcik,B.J. Robinson,D.A. Thompson,Peter Mascher +7 more
TL;DR: In this article, the influence of the cap stoichiometry on QWI has been analyzed and it has been found that the magnitude of the blue shift strongly depends on the stoichiometric of the dielectric film.
Journal ArticleDOI
Visualization of melanoma tumor with lectin-conjugated rare-earth doped fluoride nanocrystals
Tetiana Dumych,Maxym Lutsyk,Mateusz Banski,Antonina Yashchenko,Bartlomiej Sojka,Rostyslav Horbay,Alexander Lutsyk,Rostyslav Stoika,Jan Misiewicz,Artur Podhorodecki,Rostyslav Bilyy +10 more
TL;DR: NPL lectin-NaGdF4:Eu3+ conjugated NC permitted distinct identification of contours of the melanoma tissue on histological sections using red excitation at 590-610 nm and near infrared emission of 700-720 nm, of potential practical significance for development of glycans-conjugated nanoparticles to be used for in vivo visualization of melanoma tumor.
Journal ArticleDOI
Carrier loss mechanisms in type II quantum wells for the active region of GaSb-based mid-infrared interband cascade lasers
Grzegorz Sęk,F. Janiak,Marcin Motyka,Krzysztof Ryczko,Jan Misiewicz,A. Bauer,Sven Höfling,Alfred Forchel +7 more
TL;DR: In this paper, the authors measured the thermal quenching of InAs/GaInSb broken gap system quantum wells as a function of the thickness of the conduction and valence band wells.
