The peak at approximately 185 cm-1 also slightly strengthens.
The XRD patterns of CaCO3 and LSS show a CaCO3 peak at approximately 29°.
Moreover, a weak but distinct peak at approximately 96 cm−1 is observed.
The peak at approximately 510 cm-1 is originating from Si-QDs.
The intense peak at approximately 8 keV originated from the copper grid.
As expected, the MOD distribution is the most diverse, with a peak at approximately 0.3.

The bulk graphite has a G peak at approximately 1,580 cm-1[36], whereas a D peak at approximately 1,350 cm-1 is seen for defective graphite [37].
The peak at approximately 285 eV corresponds to C 1s peak of an sp2 C or sp3 C [21], and the small peak at approximately 289 eV corresponds to a carbonyl carbon (C = O) [22].
A peak at approximately 3,445 cm−1 is attributed to O-H stretching vibration of adsorbed water molecules and structural OH groups, and a peak at approximately 1,647 cm−1 is ascribed to C=C bending vibrations.
As shown in Fig. 3a, the as-grown QDs emit a dominant peak at approximately 1.02 eV (λ = 1.22 μm) and an additional peak at approximately 1.09 eV (λ = 1.13 μm).
