Talk:Aluminium gallium nitride

Is this one or a range of compositions
Since in LEDs it can produce a range of wavelengths it seems likely to be a variable composition alloy/mix like Aluminium gallium arsenide. Could be clearer and with better sources. - Rod57 (talk) 13:20, 2 November 2016 (UTC)
 * says it is variable composition. eg "AlxGa1-xN bandgap can be tailored from 4.3eV (xAl=0) to 6.2eV (xAl=1)" - Rod57 (talk) 13:26, 2 November 2016 (UTC)
