In recent years, there has been a resurgence of interest in graphene quantum dots ( i.e. large polycyclic aromatic hydrocarbons) in particular due to their interesting properties as single quantum emitters. Here, we report on a thorough study of a…

This paper assesses a new temperature measurement method at the micro-scale at high throughput. This non-invasive method is based on laser-induced fluorescence of highly monodisperse dye-doped flowing microdroplets in microfluidic channels. Laser…
Using femtosecond transient absorption (fs-TA), we investigate the hot exciton relaxation dynamics in strongly confined lead iodide perovskite nanoplatelets (NPLs). The large quantum and dielectric confinement leads to discrete excitonic transitions…
Photoluminescence imaging has become a standard method to characterize solar cells. However, performing some quantitative analysis of this technique requires the assumption of uniform local absorptivity, which cannot be directly measured using…

We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a standard spin noise spectroscopy (SNS) experiment. We show that…

The objective of the proposed macroscopic quantum resonators (MAQRO) mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations of physics in macroscopic quantum…

Nanographene materials are promising building blocks for the growing field of low-dimensional materials for optics, electronics and biophotonics applications. In particular, bottom-up synthesized 0D graphene quantum dots show great potential as…
