Abstract :
GaN:Er prepared by metalorganic molecular beam epitaxy shows intense 1.54 /spl mu/m photoluminescence (PL) at room temperature. Efficient below-gap absorption bands have been identified using photoluminescence excitation spectroscopy. An infrared hybrid InGaN-GaN:Er LED operating at 1.54 /spl mu/m has been demonstrated. Even though the resulting emission at 1.54 /spl mu/m was weak, it shows that the electroluminescence from InGaN can be used to excited Er ions in GaN.
