By Laser ablating the pure boron and phosphorus powders and their mixture, abundent Bn±, Pn±and BnPm±cluster ions have been produced and recorded subsequently by the time-of-flight mass spectrometers. It is found that almost all Bn± observed in this experiment have a similar structure, which is believed to be the close packed structure. The magic number for Pn±is 8, which is one of their structural units. It is possible that some Pn±, as well as some BnPm± cluster ions, may have a ring structure. All Pn±,...

The magic number for Pn±is 8, which is one of their structural units. It is possible that some Pn±, as well as some BnPm± cluster ions, may have a ring structure. All Pn±, Bn± and BnPm± cluster ions have a strong tendency to have their electrons paired.

在高真空中以脉冲激光束溅射单质硼、磷及其混合物,产生了非常丰富的B_n~±,P_n~±与B_nP_m~±.对飞行时间质谱的分析发现:实验产生的硼原子簇离子基本上为同一构型,可能为密堆积的结构;磷原子簇的基本结构单元为P_8;磷与硼磷簇离子中可能存在平面环的类芳香性稳定结构;所有这些簇离子均有使其所有价电子成对的强烈倾向.

(m = 1 ~21, n= 1 ~2O) and (n = 1 ~ l5, m = 1 ~ 13 ) were generated by laser ablating the mixture of gold and red phosphorus powders, and their mass spectra were recorded by a time-of-flight mass spectrometer. The mass spectra were analyzed and the mass distributions of the binary cluster ions were studied as a function of the cluster size.The relative signal intensities of most observed cluster ions exhibit even/odd alternation.With increase of the cluster size, increment of clustering phosphorus...

(m = 1 ~21, n= 1 ~2O) and (n = 1 ~ l5, m = 1 ~ 13 ) were generated by laser ablating the mixture of gold and red phosphorus powders, and their mass spectra were recorded by a time-of-flight mass spectrometer. The mass spectra were analyzed and the mass distributions of the binary cluster ions were studied as a function of the cluster size.The relative signal intensities of most observed cluster ions exhibit even/odd alternation.With increase of the cluster size, increment of clustering phosphorus atoms, m, is much less than that of clustering gold atoms, and the distribution of m for the same m of tends to be narrower. The results suggest that, at least in the larger cluster ions, the clustering gold atoms are bonded together to form the core of the clusters.

以高能量密度的脉冲激光束在高真空中直接溅射金粉和红磷的混合物,产生了丰富的金-磷二元原子簇正负离子(m=1~21,n=1~20)和,记录了它们的飞行时间质谱.这些簇离子的相对信号强度大都呈现奇偶交替的变化规律.随着成簇原子数的增加,簇离子组分中磷的相对含量逐渐减少,对应于相同成簇金原子数的成簇磷原子数分布范围变窄,簇离子的结构与性质逐渐由简单络离子向其宏观凝聚态化合物转化.在较大的簇离子中,成簇金原子很可能相互成键,构成簇离子的核心

The (100) InP samples were implanted with 300keV Er ions to a dose of 7×10 14 cm -2 at room temperature.The samples were put in an evacuated quartz ampoule together with phosphorus powder and annealed at 600℃、650℃、700℃、750℃、800℃ for 20h,respectively.The Er distribution in InP crystal are observed by secondary ion mass spectroscope (SIMS). The result show that the Er profile for both as implanted and annealed samples is nearly the same. The Er radiated 1.54μm luminescence peak has been observed in Er doped InP at 77K. The mechanism of the influence of annealing temperature on intensity of PL from Er implanted InP is propiosed in this paper.
