This work combines hyper-Rayleigh scattering (HRS) experiments performed in the NIR range (1.30 and 1.60 μm) quantum chemical calculations to provide a comprehensive description of second harmonic generation (SHG) responses donor-acceptor Stenhouse adducts (DASAs). Representative derivatives three generations DASAs, which differ by nature their electron-donating withdrawing moieties also include clickable species, have been synthesized photoswitching behavior fully characterized. The HRS...

Magneto-optical effects are attracting wide interest and found in various applications, including magnetic field sensors, optical modulators, isolators, switches. In this work, we have revisited the all-optical inverse Faraday effect (IFE) method to measure rotation angle determine Verdet constant of diamagnetic/paramagnetic liquids solutions. We show that by using a tunable picosecond laser source generated IFE enables one reach flux densities range 1–100 T, levels comparable or higher than...

Spin coating stands out as the most employed thin-film deposition technique across a variety of scientific fields. Particularly in past two decades, spin coaters have become increasingly popular due to emergence solution-processed semiconductors such quantum dots and perovskites. However, acquiring commercial from reputable suppliers remains significant financial burden for many laboratories, particularly smaller research or educational facilities. Prompted by simple mechanical principles...

Abstract Magneto-optical properties are wide and span various applications such as magnetic field sensing, imaging technologies, security encoding... In this work, we have revisited the all-optical Inverse Faraday effect method to measure rotation angle determine Verdet constant of diamagnetic/paramagnetic liquid solutions. We show that using a picosecond laser source enables reach flux densities in liquids range 1-100 T with average power ranging below 10 mW, levels which comparable or...
