An ultra-violet light-emitting diode (LED) array,, and method for fabricating same with an AlInGaN multiple-quantum-well active region,, exhibiting stable cw-powers. The LED includes a template,, with an ultraviolet light-emitting array structure on it. The template includes a first buffer layer,, then a second buffer layer,, on the first preferably with a strain-relieving layer in both buffer layers. Next there is a semiconductor layer having a first type of conductivity,, followed by a layer providing a quantum-well region,, with an emission spectrum ranging from 190 nm to 369 nm. Another semiconductor layer having a second type of conductivity is applied next,. A first metal contact,, is a charge spreading layer in electrical contact with the first layer and between the array of LED's. A second contact,, is applied to the semiconductor layer having the second type of conductivity, to complete the LED.
