I mean — NC: No, I'm not — DH: No, no.
We also demonstrate that α-Sn can be stabilized at room temperature in the form of free-standing NCs with no need of a supporting matrix, which is also unprecedented to the best of our knowledge.
Instead, for larger NCs no blue-shift is observed.
No such NCs were obtained by direct oxidation forTG < 900 °C.
Au NCs show no emission (Figure1d), and the strong emission peak of the etched Au NCs was observed at approximately 650 nm after natural etching at RT (Figure1c).
As shown in Figure1b, the absorption spectrum of the etched Au NCs has no absorption band after natural etching at RT.
Table 2 Lattice constants and elastic strain of the Pb NCs in Si Sample no.
A reference SiO2/Si sample with no metal NCs was prepared for comparison.
NCS = no concentrate supplement prior to abrupt weaning (n = 10).
CS = concentrate supplement prior to abrupt weaning (n = 10), NCS = no concentrate supplement prior to abrupt weaning (n = 10).
