EXCITON RADIATION PECULIARITIES OF RED GALLIUM-PHOSPHIDE LEDS
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2016, Vol 13, Issue 1
Abstract
Electroluminescence spectra of red GaP light-emitting diodes were investigated. Besides the main emission line hν = 1.845 eV, it was detected the additional short-wave component hν = 2.206 eV the existence of which is connected with donor-acceptor transitions between Zn-Sn pairs. It was observed intensity increase of this line at low currents (I < 50 mA) and fall for high currents (I > 90 mA) due to the thermal effect. The nature of the spectral lines anomalous broadening was discussed.
