A research team led by researchers from Osaka University created an aluminum-nitride device that can convert visible light into deep-ultraviolet light through the process of second harmonic generation. This work can lead to the development of practical devices that can sterilize surfaces with ultraviolet radiation while using less energy.

Osaka Metropolitan University scientists succeeded in directly observing how LECs—which are attracting attention as one of the post-organic LEDs—change their electronic state over time during field emission by measuring their optical absorption via lamp light irradiation for the first time. This research method can be applied to all light-emitting devices, including not only LECs but also organic LEDs. This method is expected to reveal detailed electroluminescence processes and lead to the early detection of factors that reduce the efficiency of electroluminescence.

Researchers have succeeded in storing electricity with the voltage generated from ferromagnetic resonance (FMR) using a nanometer-thin magnetic film. Exploring the storage characteristics of the commonly used iron-cobalt and iron-nickel alloy thin films, they found that by controlling the thermal conditions of the thin film to be within FMR excitation range, energy can be stored by all the electromagnetic waves that surround us – including Wi-Fi.
