掺杂的

Another important result is that, which can be easily drown from the figure of probabilities of the states vs pump power with different x, or the common logarithm figure of the populate probabilities vs x , the increasing of the concentration of Er ions increase both energy transfer which populate the state and the cross relaxation process which depopulate the state, but the total result is that ion number of high lying states increase with concentration.

从不同掺杂浓度下各态布居几率或粒子数与光强的变化关系图可以看出，虽然掺杂离子浓度的增大同时增强了产生上转换荧光能态布居的能量迁移上转换过程和消耗该能态布居的交叉驰豫过程，但两者竞争的结果是较高的掺杂浓度对产生高能激发态的粒子数有利。

After comparing with the thermal conductivity under two different conditions, the thermal conductivity with vacancy is lower than that with Kr, which accounts for phonon scattering on impurities due to lattice strain is stronger than that due to differences in mass between the defect and the surrounding matrix.

模拟结果显示，温度在20~80K之间，考虑热膨胀时的导热系数比晶格常数固定时的值要低，但随温度变化的关系更加接近实验值时的情况；比较固体氩中不同掺杂时导热系数大小，发现同样掺杂浓度条件下，掺空穴时材料导热系数比掺氪时低，说明掺杂时由于晶格不匹配引起的声子散射比不同质量引起的散射更重要。

Cu doped ZnO thin film can detect 100 ppb propyl alcohol vapor, while Mn doped ZnO thin film exhibits high sensitivity to NH3 and H2O vapor.Furthermore, the photoluminescence properties of ZnO and Tb doped ZnO thin films, heat-treated in different atmospheres, were carried out.

It showed that the La stoichiometric number X has obvious impact on the structure and the CV curves; the structure was attected by the synthesis temperature and Nd stoichiometric number X; By the EIS curves of the different potential, it showed that the resistance decreased with the increase of the potential in the doping thulium elements Nd experiment.

稀土掺杂结果表明，La的掺杂量对材料结构和循环伏安曲线有明显影响；反应温度和Nd的掺杂量对材料结构有影响；不同电势下材料的掺Nd材料的交流阻抗图谱表明，随着电势的升高，体系的电阻减小。

Also the phase transition temperature from hexagonal ZnTiO_3 phase to cubic Zn_2TiO_4 was lowed by adding V_2O_5. It was noticed that V enriched in the boundary of the exaggerated grains, while not be detected in the inner of exaggerated grains or in the boundary of small grains. At sintering temperature 50℃, orthotitanate phase Zn_2TiO_4 in zinc titanate ceramics with ≤1.00wt% WO_3 additions became major phase, while zinc metatitanate ZnTiO_3 became major phase with ≤1.00wt% WO_3 additions.

结果表明：单独掺杂V_2O_5和WO_3有效降低了陶瓷烧结温度，900℃烧结的掺杂0.75wt%V_2O_5钛酸锌陶瓷密度可达理论密度的96.1%，930℃烧结的掺杂3.00wt%WO_3钛酸锌陶瓷的密度达理论密度的95.2%；V_2O_5的添加使六方相ZnTiO_3的分解温度从900℃降到了850℃以下，V_2O_5富积于陶瓷体的晶界处，在V_2O_5富积区附近产生了异常长大的晶粒。

We present here the results of our current efforts on: 1. ZnO nanoparticles of different sizes were prepared by hydrothermal method. The effect of polyethylene pyrrolidone addition on the particles size has been studied.

另外，在对ZnO进行掺杂研究时发现，掺杂物质的类型和其纳米范围内的量子尺寸效应对功能材料的性能有着很大的影响，所以对ZnO掺杂物质种类和尺寸的研究非常重要。

Further experimental investigation and theoretical analysis on the structure and properties of undoped and doped polyaniline are carried out by using several inspecting methods and instruments.

利用有机磺酸对三种形态的本征态聚苯胺进行了系统的掺杂，并通过理论计算和X射线光电子能谱对掺杂机理进行了分析研究，提出聚苯胺的掺杂是由两步完成的模型。

This, it would be necessary only to make a little ball of earth that can be accurately weighed ; then we could easily calculate how many times the earth is larger than this little ball; and by so doing, we might tell, at one's fingerends, that — if we suppose the little earth-ball to weigh a hundred-weight — the whole globe, being so many times larger, must weigh so many hundred- weights.

可是，这样的做法极可能误导我们。因为一切取决于制造小球的物质。如果用酥松的泥土制造小球，它的重量就小；如果泥土中掺杂石头，它的重量就大一些；如果掺杂金属，取决于掺杂金属的种类，它的重量将更大。

In the paper,the effect of the variety and concentration of the dopant on the property of Zinc seleno sulphide based pigment was researched,and the principle selecting ideal dopant discussed.

The result of research indicates the In-doped mol proportion of 4% improves the structure of thin films effectively so as to increase its ultraviolet-visible light transmissivity remarkably; the Sb doping of 7% comes into being more free electrons to make its sheet resistance reduced; the P doping of 2% further enhances its conductance by reason of the forming of quasi-continuous doping energy band.
