Left: Thermal stability of the TiO2@Au and SiO2@Au SHINs: the Rh6G 1362 cm−1 was compared with its initial value after the specified heat treatment for 3 h. Right: Thermal stability of the TiO2@Au and SiO2@Au SHINs: the intensity of pyridine at 1008 cm−1 was related to the Rh6G intensity at 1364 cm−1 to test the uniformity of the coating. (λ=785 nm; P=2.0×105 W cm−2). Additional information can be found in Figures S18–23 in the Supporting Information.
