Abstract(in English) | We have grown Eu-doped GaN/AlGaN multiple quantum well (MQW:Eu) structures by organometallic vapor-phase epitaxy, and investigated their luminescence properties. The satellite peaks owing to GaN/AlGaN multiple quantum well structures were observed in X-ray diffraction patterns for the MQW:Eu samples. The photoluminescence (PL) spectra of the MQW:Eu samples exhibited enhancement of Eu luminescence peak intensity and broadening of the peak width compared with Eu-doped GaN (GaN:Eu) grown using the same condition. The integrated PL intensity in MQW:Eu was four times higher than that in GaN:Eu. Photoluminescence excitation (PLE) spectra of MQW:Eu indicated that the enhanced Eu luminescence originated from Eu^<3+> ions in the GaN well layers. |
