We most often witness the presentation of quantum dots in viles or containers which are excited via UV light. I am more interested in their electrical excitation. Could I simply take a sample of QDs from one of those viles and passing an electrical current through that sample excite the quantum dots to produce their light? QDs are often supplied suspended in toluene....Again....could I simple pass electrical current through such samples and expect the production of light via the QDs? If some sort of preparation of the colloidal QDs were necessary in order to achieve electrophospherescence; what might that be and would I expect the production of more light than with application of UV . In general terms....I am interested in the electrical excitation of QDs in liquid form/suspension.
