Electroless Copper Deposition Using Sodium Hypophosphite as Reductant

研究了以次磷酸钠为还原剂、硫酸镍为再活化剂的化学镀铜工艺和镀层结构,指出工艺的基本特性。结果表明,在含有次磷酸钠和硫酸镍的镀液中,化学镀铜过程可以持续进行并呈现自催化特性;只有在合适的镀液pH范围内才可获得铜镀层;铜镀层为面心立方结构,没有明显的晶面择优取向现象,镀层结构的晶面间距d和晶胞参数a与标准Cu粉末的相比均较大,说明铜镀层仍存在应力和缺陷。The primary characterstics for the process of electroless copper deposition, using sodium hypophosphite as reducing agent and nickel sulfate as re-activation agent, and the deposit structure were studied. The results showed that in the solution containing sodium hypophosphite and nickel sulfate the copper deposition was sustainable and was presented in self-catalyzation. The deposit could only be obtained in a proper pH range. The deposit was in face-centered cubic structure without obvious crystal face preferred orientation. Its lattice distanced and lattice parameter a were larger than those of standard copper powder, which indicated that the obtained deposit was still present internal stress and defects

Studies on Cu-Ni alloy electroless plating using sodium hypophosphite as reductant

研究了以次磷酸钠为还原剂的化学镀铜过程。分析了温度、pH、硫酸镍含量对化学镀铜沉积速率的影响及镀层的表面形貌和结构。结果表明,沉积速率随着镀液温度、pH和N i离子浓度的提高而增大。镀层组分含量和XRD实验结果表明镀层为铜镍合金,呈面心立方结构,晶面间距d与晶胞参数a与标准Cu-N i的相比略大。SEM实验表明,镀层表面形貌为团粒状,颗粒大小较不均匀。The process of the electroless copper plating(using) sodium hypophosphite as reductant was studied.The influences of temperature,pH,nickel sulphate content on deposition rate of copper electroless plating as well as the surface morphology and structure of the deposit were(analyzed.)The results show that the deposition rate is(accelerated) with increasing bath temperature,pH value and the concentration of nickel ion.Both deposit composition and XRD results indicate that the deposits are Cu-Ni alloy with face-centered cubic structure.Its structural parameters of d and a are slightly larger than that of the standard Cu-Ni(alloy).SEM experiment displays that the deposit has a(surface) morphology of granular structure with uneven grain sizes.国家科技攻关计划项目(2004BA325C

Email: [email protected]; Tel: +86-592-2189023[中文文摘]表面增强拉曼光谱(SERS)具有极高的检测灵敏度,通过检测吸附分子的SERS信号,可以获得表面吸附分子的结构以及可能发生的反应.在拉曼激发光源的辐射下,在碱性溶液中,银纳米粒子表面吸附的对氯硝基苯(PCNB)的SERS光谱与其固体的常规拉曼光谱相比,出现异常SERS谱.通过采用密度泛函理论(DFT)计算,对PCNB以及可能的偶联产物p,p′-二氯偶氮苯(DCAB)进行理论分析以及谱峰归属,发现这些异常峰来自其偶联产物DCAB的偶氮C-N=N-C基团的基频振动. [英文文摘]Surface-enhanced Raman spectroscopy (SERS) on silver nanoparticles is highly sensitive because of surface plasmon resonance. We have studied the structures and photoinduced chemical reactions of p-chloronitrobenzene (PCNB) molecules adsorbed on silver nanoparticles using a combination of SERS and density functional theory (DFT) calculations. When the PCNB molecules are adsorbed to the surface of silver nanoparticles in alkaline solution, the SERS spectra are very different from the normal Raman spectra of PCNB. Comparison of the DFT simulated Raman spectra of PCNB and p,p-dichloroazobenzene (DCAB) indicates that the new peaks in the SERS spectrum of PCNB adsorbed on silver nanoparticles arise from the azo (C－N＝N－C) group of DCAB.国家自然科学基金(20973143, 91027009, 21021002);国家重点基础研究发展规划项目(973)(2009CB930703);厦门大学(2010121020
