Dimensional characterization of cadmium selenide nanocrystals via indirect Fourier transform evaluation of small-angle X-ray scattering data

Autor: Bilal Temel, Julian Cedric Porsiel, Alfred Schirmacher, Georg Garnweitner, Egbert Buhr

Publikováno v: Nano Research. 12:2849-2857

The correlation of single-particle imaging and absorption spectroscopy made the development of sizing curves possible and enabled rapid size determination of semiconductor nanocrystals based solely on optical properties. The increasing demand and pro

Traceable Size and Size Distribution Calibrations of Nanoparticles

Autor: Thorsten Dziomba, Egbert Buhr, Michael Krumrey, Harald Bosse, C. G. Frase

Publikováno v: Chemie Ingenieur Technik. 89:239-243

Quality control of nanoparticle production processes requires traceable calibration methods for size and size distribution which are presented and discussed in this article. The main focus is on the one hand the application of small-angle X-ray scatt
