متن کاملEnhanced biological cathodoluminescence
We have combined the specificity of antibody labeling, the power of fluorescence detection, and the resolution of scanning electron microscopy (SEM) to identify antigenic sites on nanometer-scale features of mammalian cells. Cathodoluminescence (CL) detection in SEM was used to locate fluorophores bound to antibodies specific for cell surface epitopes. Sample preparation and instrument setup we...
متن کاملPhoton bunching in cathodoluminescence.
We have measured the second order correlation function [g^{(2)}(τ)] of the cathodoluminescence intensity resulting from the excitation by fast electrons of defect centers in wide band-gap semiconductor nanocrystals of diamond and hexagonal boron nitride. We show that the cathodoluminescence second order correlation function g^{(2)}(τ) of multiple defect centers is dominated by a large, nanoseco...
متن کاملMapping of Weak Cathodoluminescence Signals
Mapping of cathodoluminescent active materials to show growth zoning, trace element variations and valence is becoming more common [1]. The desire to capture cathodoluminescence (CL) maps from samples that are weakly emitting arises for two reasons. Firstly, the chemical spatial resolution in maps is related to the accelerating voltage used, and the drive for higher resolution x-ray maps is lea...
متن کاملIntroduction: special issue on cathodoluminescence.
Cathodoluminescence ~CL! microanalysis provides high-sensitivity spectra and high-resolution images associated with impurity and structural defects at the nanoscale and from luminescent materials including minerals, semiconductor, and dielectric/insulating materials. Cathodoluminescence is the non-incandescent emission of light ~photons! emitted from materials excited by an electron beam. CL ph...
