Figure 4: Process monitoring with E1 transition assessment of phase.
From: Optical determination of crystal phase in semiconductor nanocrystals
(a) Absorption spectra of ZB CdSe NCs subject to photochemical etching, normalized by intensity at 4 eV. Curves are colour-coded to indicate the continuous shift in E0 to higher energy, with little shift in E1. (b) Trends in E0 (black solid circles) and E1 (blue open circles) transitions as the NC size decreases. Energy regions for E1,ZB and E1,WZ are indicated by red and green shading, respectively. Lines connecting data points are guides to the eye.
