(a,b) Photographs and (c,d) relative turbidity changes of the Nd2O3 plate gels (a and c) and Yb2O3 plate gels (b and d) in water at 28 °C under intermittent irradiation with 808 and 980 nm light at 3 W cm−2. The dimensions of the plate gels are 5 mm × 5 mm with a thickness of about 1 mm. The turbidity changes were measured with 532 nm laser light at 1 mW. The arrows indicate the centres of the irradiation spots.
