Visible Luminescence of the InGaN/GaN Ultraviolet Light-emitting Diodes 365 nm [PDF]

Журнал нано- та електронної фізики, 2017
Visible electro- and photoluminescence of the ultraviolet LEDs (пЃ¬В пЂЅВ 365В nm) was studied. It is established that at nitrogen temperature yellow electroluminescence is absent and occurs when the current or temperature increases.
