Summary: A self-driven and energy-saving Ni anode-based electrochromic device (ECD) using Prussian blue as electrochromic material is developed. It can be colored by solar energy during the day and spontaneously bleach at night using the internal redox potential, without any extra energy input. Compared to ECDs with high Ni2+ or high K+ concentration in the electrolyte, the Ni-based ECD with equal amount of K+ and Ni2+ exhibits higher optical contrast, faster coloration response time, and better stability.

Summary: Conventional organic optoelectronic devices have low carrier mobility due to disorder. This study presents monolithic integrated triclinic crystal rubrene light-emitting diodes (LEDs) with engineered functional additives. The crystalline LEDs show superior charge transport, operational stability, and long-term stability. However, the crystalline phase reduces the overall performance compared to amorphous rubrene in terms of exciton dynamics and annihilation rates. The potential applications of rubrene and/or its derivatives crystalline films for improving the performance of organic and hybrid optoelectronic devices are discussed.

Summary: This study combines spectroscopic measurements with photothermal techniques to accurately determine the photoluminescence quantum yield (PLQY) of six fluorescent molecules in low concentration solutions. The measurement method demonstrates high reliability and can detect phonon-assisted optical upconversion when the photon energy is below the photothermal threshold. It is found that perylene red solution has the highest PLQY, while the presence of low energy sub-gap impurities in perylene orange solution prevents upconversion.
