Fig. 2: ToF-SIMS profiles obtained from the analysis of the surfaces of glass A_dSn before (solid lines) and after 470 days of alteration (dashed lines) at 70 °C and pH = 2.4.
From: Surface treatments on commercial glasses: durable impact on the retention of lead, barium and boron
The comparison of results obtained for Na, K, Si, Pb are given in (a–d), respectively. The yellow shaded area represents the depth occupied by the tin oxide coating. The ions displayed represent the species detected by the mass spectrometer after sputtering and the signals are normalized to the total ion count as indicated by Eq. (2).
