Matrix-Assisted Pulsed Laser Thin Film Deposition by Using Nd:YAG Laser
Figure 3
(a) Reference IR spectra, performed in reflectance mode, in the range 900–1600 cm−1 of the substrate (a glass slide) without (black dashed line) and with a dried drop of PEG (red full line). The arrows show the C–O–C aliphatic ether antisymmetric stretching vibration bands in the range 1150–1060 cm−1 and the C–OH deformation vibration absorption in the range 1400–1300 cm−1. (b) and (c) show typical spectra carried out on PEG films deposited on glass slides with MAPLE technique using laser radiation at 532 nm and 355 nm, respectively.
