Photoluminescence study of Ge nanocrystals irradiated by reactor neutron flux

Formation and characterization of varied size germanium nanocrystals by electron microscopy, Raman spectroscopy, and photoluminescence

“…The emission wavelengths can also be tuned between 1548 nm and 1905 nm by changing the doping levels [13]. Ge ncs were reported to emit between 563 nm and 1548 nm explained by the quantum confinement effect (QCE) [15][16][17][18][19][20][21]. In addition, many results have been published covering the entire visible and ultraviolet (UV) ranges related to various defects or interface of Ge ncs with matrix [18,[22][23][24][25][26][27].…”
