Anion-Responsive Metallopolymer Hydrogels for Healthcare Applications
Metallopolymers combine a processable, versatile organic polymeric skeleton with functional metals, providing multiple functions and methodologies in materials science. Taking advantage of cationic cobaltocenium as the key building block, organogels could be simply switched to hydrogels via a highly efficient ion exchange. With the unique ionic complexion ability, cobaltocenium mo...

Optical absorption properties of Ge2–44 and P-doped Ge nanoparticles
The optical absorption properties of non-crystalline and crystalline Ge nanoparticles with the sizes from ～2.5 to 15 ? have been studied at the B3LYP/6-31G level using time-dependent density functional theory. Hydrogen passivation and phosphorus doping on some selected Ge nanoparticles were also calculated. With the increase of cluster size, the optical absorption spectra of the non-crystall...

First-principles insight into photoelectronic properties of Ge-based perovskites
The crystal configuration, electronic structure, charge-carrier transport, and optical properties of Ge-based MAGeX3 perovskites (MA = CH3NH3+; X = Cl?, Br?, and I?) and AGeI3 (A = Cs+, MA, FA (HC(NH2)2+), MO (CH3C(NH2)2+), and GA (C(NH2)3+)) were investigated using first-principles theory. The results showed that the increase in Ge–X bonds (from Cl? to I?) in MAGeX3 increased the volumes, weak...

Ge/Si 纳米多层膜的光致发红光研究
关键字：Ge/Si 纳米多层膜,PL 谱,红光
采用磁控溅射设备，当衬底温度为500℃时，在Si(100)基片上磁控溅射生长Ge/Si 多层膜样品。使用Raman 和低角X 射线技术对样品进行检测和研究。在红光波段对样品的光致发光进行了研究，结果表明在红光波段发光峰位来源于薄膜的非晶结构及其薄膜所产生的缺陷；发光峰的强度和峰形受Ge 子层和Si 子层厚度的影响。

离子束溅射Si/Ge 多层膜的界面结构研究
关键字：Si/Ge 多层膜, 界面结构, 离子束溅射
采用离子束溅射技术，在玻璃衬底上制备了不同周期数的Si/Ge 多层膜样品。通过Raman 光谱和X射线小角衍射对薄膜进行了表征和分析，发现随着生长周期数的增加，层与层之间的互扩散效应逐渐减弱，界面结构逐渐清晰，生长周期为25 的样品界面最平整。

磁控溅射沉积的Ge/ZnO复合多层膜的光致发光特性研究
关键字：磁控溅射 Ge/ZnO多层膜 光致发光
采用交替溅射Ge和ZnO靶的方法在Si (100) 单晶基片上沉积了Ge/ZnO复合多层膜，并对其在空气中不同温度下进行了快速加热处理。在高温处理中部分Ge成分会被氧化转变成Ge的氧化物，XRD结果表明所制备的薄膜是由ZnO、Ge、GeO和GeO2多晶颗粒组成的复合薄膜，且随着温度的升高晶粒的尺寸加大，结晶度提高。光致发光谱的测量显示，经过高温处理过的Ge/ZnO复合多层膜可以在395nm左右发出强的紫光，随着温度的增加紫峰变尖锐且强度...
