Specialists NTU and NTHU have created organic light-emitting diodes operating in the near infrared region with record efficiency

A joint team of researchers from NTU (National Taiwan University) and NTHU (National Tsing Hua University) synthesised a material based on platinum, which allowed us to create an organic led that emits in the near infrared (IR OLED). The emission wavelength of 740 nm.

Conventional OLED materials, the band gap decreases with a shift to infrared region, so the emission efficiency decreases. New material addresses this shortcoming. The resulting LEDs have demonstrated a record high efficiency value.

Applications of IR OLED related automotive proximity sensors. In addition, the ability of near-infrared radiation to penetrate tissue makes the new LEDs are in demand in medical devices.
