Annotation Visible electro- and photoluminescence of the ultraviolet LEDs (  365 nm) was studied. It is established that at nitrogen temperature yellow electroluminescence is absent and occurs when the current or temperature increases. The light output power and luminous efficiency of the yellow electroluminescence in the 450-740 nm range were measured. At temperature decreasing an increase of the luminescence intensity in the spectrum range 393-460…490 nm is observed.
