Figures

Image of FIG. 1.
FIG. 1.

(a) Absorption and fluorescence spectra of the samples [nanodots (QDs), nanorods (NRs), and tetrapods (TPs)] at room temperature (solid lines) and at (dotted lines). (b) Fluorescence spectra of the samples at different temperatures (excitation at ).

Image of FIG. 2.
FIG. 2.

Maximum of the fluorescence band of NDs (circles), NRs (squares), and TPs (triangles) as a function of temperature. Solid lines are the fits according to Eq. (1).

Image of FIG. 3.
FIG. 3.

FWHM of the fluorescence bands of the CdSe NDs (circles), NRs (squares), and TPs (triangles). Solid lines are the fits according to Eq. (2) for NDs and TPs, and Eq. (3) for NRs. The inset presents results for NRs of different sizes [ (diameter of ), (diameter of ), and (diameter of )].

Tables

Generic image for table
Table I.

Parameters used in the fit of the photoluminescence energy as a function of temperature (Fig. 2) with Eq. (1).

Generic image for table
Table II.

Parameters used in the fit of the full width at half maximum of the luminescence band as a function of temperature (Fig. 3) with Eqs. (2) and (3) [ was fixed to the literature value (Refs. 5 and 20)].
