摘要:
A semiconductor nanocrystal compound capable of linking to one or more affinity molecules comprising (1) one or more semiconductor nanocrystals capable of, in response to exposure to a first energy, providing a second energy, and (2) one or more linking agents, having a first portion linked to the one or more semiconductor nanocrystals and a second portion capable of linking to one or more affinity molecules. One or more of semiconductor nanocrystal compounds linked to one or more affinity molecules to form a semiconductor nanocrystal probe capable of bonding with one or more detectable substances in a material being analyzed, and are capable of, in response to exposure to a first energy, providing a second energy. The probe is capable of emitting electromagnetic radiation in a narrow wavelength band and/or absorbing, scattering, or diffracting energy when excited by an electromagnetic radiation source of narrow or broad bandwidth, or a particle beam. The probe is stable to repeated exposure to energy in the presence of oxygen and/or other radicals.

摘要:
Embodiments relate to a quantum rod composition (100), a quantum rod film (250), a display device (300) with a quantum rod film (370), and a method of forming a quantum rod film (370). The quantum rod film (250) includes a plurality of quantum rods (210) and a polymer (220) with a dipole side chain (224). Responsive to an external electric field (E), the major axis of the quantum rods (210) and an axis of the dipole side chain (224) arranges in the same direction. The display device (300) includes a plurality of pixel and common electrodes (350, 352) for generating an electric field, and a backlight unit (307) positioned under a first substrate (330). Responsive to receiving light from the backlight unit (307), the quantum rod film (370) emits light polarized in a direction parallel to the major axis of the quantum rods (310).
