Table 2 PL peak energy and nanocrystal size for SiO₂ embedded Ge NCs

From: Optical and electrical properties of undoped and doped Ge nanocrystals

Sample name	PL peak details		d_NC (TEM) nm
	Peak position (eV)	FWHM (eV)
'RS-1'	2.31-2.58	0.38-0.68	2.4 ± 0.8
'RS-2'	2.11-2.8	0.30-0.91	5.3 ± 1.3
'RS-3'	1.88	0.24	10 ± 3

d_NC, nanocrystal diameter; FWHM, full width at half maxima; 'RS-1', 'RS-2', and 'RS-3', sample structures defined in Table 1; PL, photoluminescence; TEM, transmission electron microscopy.
