rare-earth ion meaning in Chinese
稀土离子
Examples
- Calculation of intensity for transitions within 4f n configuration of rare - earth ions in crystals
组态内光子跃迁强度的计算 - It is thought that the exciplex ' s emission is eliminated completely by modulating the transient excited state of exciplex thought varying the ratio of two molecules and by action from the excited state level of rare - earth ions
对于稀土配合物，可以通过控制混合层中的分子比率调制激基复合物的瞬间激发态能级位置，使其与稀土离子的激发态能级匹配，将激基复合物完全消除。 - So that film ybig / ggg was grown in proper temperature , then film ybilg was grown onto ybig / ggg . to improve the magneto - optical properties of films , film ybig was grown onto substrate ybilg which was sliced from garnet ybilg and polished . the tests of magneto - optical properties of the grown thin films showed that through combining two types of rare - earth ion garnet films with opposite signs of farady rotation temperature coefficients , high faraday temperature stability was reached due to temperature compensation effect , which indicated of great potential for application
反复实验结果表明， ybiig薄膜的最佳外延温度区间比ybig薄膜的低约10以上，因此，根据实验结果选择合适的温度，我们先在ggg上外延生长ybig薄膜，然后在ybig上再外延ybiig薄膜，成功制成了ybiig ybig ggg复合膜结构；为了进一步提高性能，我们还将以前生长的ybiig单晶定向切割制为基底，在其上进行复合外延。 - The discovery of the colossal magnetoresistance ( cmr ) in hole - doped perovskite manganites ra1 - xmxmno3 ( ra is a trivalent rare - earth ion and m is a metal ion ) has attracted much attention since 1989 due to not only its technological applications in magnetic recording and sensor , but also the effect of the strong correlation concerning metal - insulator transition in the field of basic research . since then , several physics models have been suggested to explain the mechanism of cmr . however , the exact mechanism of cmr remains to be done
自1989年在掺杂钙钛矿型锰氧化物ra _ ( 1 - x ) m _ xmno _ 3 (其中m为金属离子， ra为三价稀土离子)中发现庞磁电阻( cmr )以来由于其在磁记录、磁传感器等方面潜在的应用前景，以及金属?绝缘体相变等所涉及的强关联效应，使该类化合物吸引了物理学界的广泛注意。 - Faraday rotation spectra was measured on samples with model cgx - 1 fr test apparatus by ourselves using the magneto - optical modulated double - frequency method . the development on magneto - optical material and devices , especially on rare - earth ion garnet , were reviewed . as a solution to the problem for temperature stabilized and wideband magneto - optical materials which could satisfy the development of magneto - optical devices for integration and miniaturization , a modified liquid phase epitaxy ( lpe ) technique was brought forward to grow thin film yb3fe5o12 onto substrate ybilg or thin film ybilg onto sustrate ybig
本论文工作包括对ybiig 、 ybig系列石榴石薄膜制备的实验构想、相图分析、制备工艺分析和配方设置，搭建了液相外延设备；比较系统地研究了ybiig 、 ybig系列石榴石薄膜的生长、测试，首次成功制备了ybig ybiig 、 ybiig ybig ggg系列复合膜，并采用xrd 、 sem 、 epma等方法对所得样品进行了结构、组分和微区形貌分析，用紫外可见光光谱仪测试了其在可见近红外波段光吸收。
