摘要: Eu3+-doped LaPO4 and Tb3+-doped CePO4 luminescent nanoparticles embedded in hybrid organosilica were patterned by two soft lithographic techniques. The role of various parameters such as solution chemistry, thermal protocols, modification the mold-substrate surface energies related to pattern shape formation adhesion substrates have been studied. shrinkage oxide patterns evolution during process was also examined. characterized with optical photoluminescence (PL) microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM). Compositional analyses carried out photoelectron spectroscopy (XPS), low-energy ion scattering (LEIS), secondary mass (SIMS). results indicated that final obtained these techniques for same material different shapes adherence substrates.
