Needs, trends, and advances in scintillators for radiographic imaging and tomography
Zhehui Wang, Christophe Dujardin, Matthew S. Freeman +17
Scintillators are important materials for radiographic imaging and tomography (RadIT), when ionizing radiations are used to reveal internal structures of materials. Since its inven…
CdS/CdSe/CdS spherical quantum wells as single-photon sources
A. Allemand, F. Kulzer, B. Mahler +2
We have synthesized CdS(1.3 nm)/CdSe(1.7 nm)/CdS(3.4 nm) spherical quantum wells with 13 nm diameter and demonstrated the first antibunching of their emission, labelling them as si…
Doping MAPbBr hybrid perovskites with CdSe/CdZnS quantum dots: from emissive thin-films to hybrid single-photon sources
Justine Baronnier, Julien Houel, Christophe Dujardin +2
We report the first doping of crystalline methylammonium lead bromide (MAPbBr) perovskite thin-films with CdSe/CdZnS core/shell quantum dots (QDs), using a soft-chemistry metho…
Optical Properties of Fully Inorganic, Spacer-Free Core/Gradient-Shell CdSe/CdZnS Nanocrystals at the Ensemble and Single-Nanocrystal Levels
Justine Baronnier, Benoit Mahler, Christophe Dujardin +2
We report the synthesis and optical characterization of fully inorganic gradientshell CdSe/CdZnS nanocrystals (NCs) with high luminescence quantum yield (QY, 50 percent), which wer…
Internal quantum efficiency of AlGaN/AlN quantum dot superlattices for electron-pumped ultraviolet sources
A. Harikumar, F. Donatini, C. Bougerol +6
In this paper, we describe the growth and characterization of 530-nm-thick superlattices (100 periods) of AlxGa1-xN/AlN (x = 0, 0.1) Stranski-Krastanov quantum dots for application…
Particle detection at cryogenic temperatures with undoped CsI
Michael Clark, Patrick Nadeau, Shane Hills +2
Scintillation at cryogenic temperatures can give rise to detectors with particle discrimination for rare-event searches such as dark matter detection. We present time-resolved scin…
Atomistic Mechanisms for the Nucleation of Aluminium Oxide Nanoparticles
Julien Lam, David Amans, Christophe Dujardin +2
A predictive model for nanoparticle nucleation has not yet been successfully achieved. Classical nucleation theory fails because the atomistic nature of the seed has to be consider…
Autocorrelation analysis for the unbiased determination of power-law exponents in single-quantum-dot blinking
J. Houel, Q. T. Doan, T. Cajgfinger +11
We present an unbiased and robust analysis method for power-law blinking statistics in the photoluminescence of single nano-emitters, allowing us to extract both the bright- and da…
YAG nano-light sources with high Ce concentration
Bruno Masenelli, Oriane Mollet, Olivier Boisron +5
We investigate the luminescence properties of 10 nm YAG nanoparticles doped with Ce ions at 0.2%, 4% and 13% that are designed as active probes for Scanning Near field Optical Micr…
