| Popis: | Polyperinaphthalene (PPN) nanoparticles are prepared by excimer laser ablation (ELA) of a 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) target or a mixture target of PTCDA with Co or TiO2 powder (PTCDA/X: X=Co, TiO2) using XeCl excimer laser beams. Enhancement of elimination reaction of side groups of PTCDA is observed by ELA of PTCDA/Co and PTCDA/TiO2. In particular, for PTCDA/TiO2, the reaction occurs at a fluence of 0.25 J cm−2 pulse−1 much lower than the case of PTCDA/Co at room temperature. Heterojunctions between the PPN nanoparticle layer and Si wafers are formed. Well rectifier property is demonstrated for the junction with n-Si substrates. Current versus voltage curve of the heterojunction with a n-Si substrate in the dark and under illumination shows the possibility of the junction as a photovoltaic cell. Furthermore, PPN nanoparticles are applied to anode electrodes for ultrathin rechargeable Li ion batteries. In situ Raman spectroscopy under lithium ion doping is performed to elucida... |
