(a) Nanoindentation profiles of silica hybrid films exposed to increasing X-ray doses and performed with a constant loading force of 0.8 mN: not exposed (black line), exposed to 188.5 (red line), 377 (blue line), 754 (green line) and 1508 J cm−2 (pink line). (b) Young's modulus (red dots) and maximum penetration depth (blue triangles) of silica hybrid films as a function of increasing X-ray dose. The lines are a guide for the eyes. |
