PROBE atomic force microscopy nanocomposite radiating elements doped quantum dot core-shell structure

摘要

1. A probe of an atomic force microscope nanocomposite radiating element doped quantum dots core-shell structure comprising a cantilever connected to a probe needle with nanometer vertex radius of curvature, which is connected with a sphere, wherein the sphere is made of glass through-pores with nanometer filled with quantum dots core-shell structure, the number of which is greater than two, and the scope is determined by the diameter and number of pores that can accommodate quantum dots without departing from their shells beyond the perimeter of the sphere circumference, the sphere is attached to the formed electrically conductive probe needle, due to threading friction top electrically conductive probe needle with nanometer radius of curvature in one of the through pore glass sphere with nanometer pores to the top exit on the other side of the sphere by a distance equal to maximum depth investigated nanokolodtsev disposed on the surface of diagnosing object, the remaining through-pores filled with quantum dots core-shell structure coated with a protective p olimernym layer transparent to the wavelength of the external excitation source of electromagnetic quantum dot core-shell structure and wavelength Stokes shift with quantum dots generated structure-obolochka.2 core. The probe according to claim 1, characterized in that the external excitation source of quantum dots is fixed at the base of the cantilever and its radiation is focused on the center of a glass sphere with nanometer pores filled with quantum dots core-shell structure.
