(a) UV–Vis transmittance spectra of silica hybrid films exposed to increasing hard X-ray doses: not exposed (black line), exposed to 188.5 (red line), 377 (blue line), 754 (green line) and 1508 J cm−2 (pink line). (b) Average transmittance of the silica hybrid films calculated in the range 230–800 nm as a function of increasing X-ray doses. The line is a guide for the eyes. |
