Diphenilamino-substituted carbazoles were used as guest compounds for the preparation of highly efficient blue organic light-emitting diodes based on the phenomenon of delayed fluorescence. It was ...

In modern devices, such as phone screens or advanced sensors, light is often generated by pairs of organic molecules, where one molecule, known as the donor, transmits electrons, and the other, ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

Abstract: We propose a non-contact method for determining phosphor/silicone temperature (phosphor temperature) in phosphor-coated light-emitting diode (pc-LED). The pc-LED with a surface mounted ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

We report on the demonstration of MOVPE-grown single nanowire InGaN/GaN core–shell light emitting diodes (LEDs) with a transparent graphene contact for hole injection. The electrical homogeneity of ...
