Optical fibers with tailored spectral response are doped with luminescent ions, rare-earth ions (re), embedded in nanoparticles (np) formed in situ in silica glass through a phase separation process. This engineering requires to understand the relation between the np composition and the re environment. In molecular dynamics, the existing interatomic potentials fail to reproduce the phase separation as experimentally observed. The system xmgo-(1-x)sio2 exhibits a domain inside of which two mixed phases coexist, mg-rich either si-rich. Such a phase separation can only be modeled by an interatomic potential that takes into account bond ionicity, and the transferability isEnabled here by the adaptation of oxygen charges according to the local e...
