While combining two metals in the same nanoparticle can lead to remarkable novel applications, the resulting structure in terms of crystallinity and shape remains difficult to predict. It is thus essential to provide a detailed atomistic picture of the underlying growth processes. In the present work we address the case of core-shell Fe-Au and Fe-Ag nanoparticles.

- * Advanced techniques like X-ray diffraction, mass spectrometry, and electron microscopy were utilized to analyze the structure of the quantum wells.
- * Photoluminescence measurements revealed that rapid annealing at 650°C improved emission quality, but higher temperatures caused degradation and blue-shifting due to issues with non-radiative centers and bismuth movement.
