Rezumat

Layered double hydroxide (LDH) thin films of Mg-Al having Mg/Al of 2.5 with/without organic chromophores (coumarin-343) or surfactant (dodecylsulfat) guest intercalated in layered double hydroxide host were deposited via pulsed laser deposition (PLD)[1,2]. Powders of intercalated compounds and of pristine LDH were obtained by coprecipitation and reconstruction, respectively. The thin films were deposited at 266, 532 and 1064 nm wavelength of a Nd:YAG laser working at a repetition rate of 10 Hz and pulse duration of 5 ns in order to find the best deposition parameters (Fig. 1). X-ray diffraction (XRD) and thermogravimetric analysis were used to analyse the homemade prepared powders. We observed that 532 nm and 1064 nm favoured the formation of a thicker film with prospective applications in photoluminescence materials or as corrosion coating on different surfaces.
