9861142 This Phase I Small Business Innovation Research project aims to obtain erbium endohedral metallofullerenes using recently developed purification processes and incorporate these materials into optical fiber and related devices with improved performance suitable for near term commercial application. Glasses activated with trivalent lanthanide ions emitting in the near infrared region are of current interest because of their potentiality as materials for high power lasers and optical amplifiers for fiber communications, and for fiber optic sensing applications. Currently, erbium doped fiber amplifiers (EDFA) are used for regeneration of optical data, enabling transmission over extremely long distances. In addition, erbium doped fiber is being investigated for use in ring laser devices for gyroscopic applications, and fluorescence of rare-earth materials such as erbium may be used to measure temperature through the relation between the fluorescent decay time and temperature. By encapsulating erbium ions in the metallofullerene Er2 @ C82, the erbium is provided an exceptionally homogeneous environment relative to silica glass. This can have the effect of increasing the excited state lifetime and corresponding laser efficiency, and can be important in upconversion lasers. Improved erbium doped materials using endohedral metallofullerenes would have immediate commercial application in erbium doped fiber amplifiers, fiber lasers, fiber ring laser gyroscopes, and other communication and sensor products, including fluorescence based temperature sensors for aircraft applications. Purified erbium endohedral metallofullerene material can be sold as raw material, and fiber preforms doped with erbium EMF could be sold to fiber manufacturers.

9861142该第一阶段的小型企业创新研究项目旨在使用最近开发的纯化工艺来获取ERBIUM内hmellyfullerenes，并将这些材料纳入光纤和相关设备，并改善了适合近期商业应用的性能。用近红外区域发射的三价灯笼离子激活的玻璃具有当前感兴趣的，因为它们作为高功率激光器和光纤通信的光学放大器的潜力以及光纤传感应用。目前，Erbium掺杂纤维放大器（EDFA）用于光学数据再生，从而可以在极远的距离内进行传输。此外，正在研究Erbium掺杂纤维，用于用于陀螺仪应用的环激光器设备，并且可以使用稀土材料（例如Erbium）的荧光来通过荧光衰减时间和温度之间的关系来测量温度。通过将金属烯烯ER2 @ c82中的Erbium离子封装，提供了相对于二氧化硅玻璃，提供了一个异常均匀的环境。这可能会产生增加激发态寿命和相应激光效率的影响，并且在上转换激光器中很重要。 使用内h金属氟列烯烯类改进的Erbium掺杂材料将立即在掺杂纤维放大器，纤维激光器，纤维环激光陀螺仪以及其他通信和传感器产品中立即进行商业应用，包括飞机应用的荧光温度传感器。纯化的Erbium内hmellyfullerene材料可以作为原材料出售，并且可以将带有Erbium EMF的纤维预形成掺杂，可将其出售给纤维制造商。
