Borate nonlinear optical single crystal surface finishing by argon cluster ion sputtering

A new rare-earth oxyborate Ba3BiPbEuO(BO3)4and the luminescence properties of the Ba3BiPbY1−xEuxO(BO3)4phosphors

“…This peak can be attributed to the B atoms bonded to oxygen atoms (B–O) in the host lattice. 59–61 The XPS spectral profile of O 1s can be deconvoluted into two components, representing different types of oxygen. The higher binding energy peak around 531.58 eV may be due to the OH and oxygen in H 2 O, which are adsorbed on the sample surface during the preparation of the sample for analysis under non-vacuum conditions, while the lower binding energy peak centered at 529.93 eV can be assigned to lattice oxygen.…”
