Schematic of the experimental setup.
Conjugation reaction chemistry of amine functionalized NP with carboxyl terminated QDs.
TEM of (a) mixed NPs and QDs and (b) NPs conjugated with QDs. Dehydration is expected to severely affect the conjugated NP-QDs complex since it may break the organic coating. However, the QDs remains preferentially distributed around iron oxide particles in (b), an indication that conjugation took place.
Examples of emission intensity vs wavelength for (a) mixed, (b) conjugated gold NP systems, (c) mixed, and (d) conjugated NP-QD systems.
Maximum wavelength vs isothermal temperature of the sample for QDs with (a) gold and (b) samples before and after the samples were subjected to rf heating.
Measured temperature during rf heating vs squared voltage for mixed and conjugated QDs with (a) gold and (b) NPs and field frequencies of 600, 700, and 800 kHz.
