查询词典 electron beam

Infrared upconversion and optical storage thin film CaS∶Eu, Sm has been successfully developed by electron beam evaporation and radio frequency magnetron sputtering. Infrared upconversion efficiency of CaS∶Eu, Sm thin films with different thickness has been investigated by using the ultrashort infrared laser pulses with different FWHM.

采用电子束蒸发和磁控溅射技术制备了具有红外上转换和光存储特性的电子俘获材料CaS∶Eu，Sm薄膜，利用不同脉宽的超短红外激光测试了它们的红外上转换效率，指出CaS∶Eu，Sm薄膜的红外上转换发光效率不仅与制备工艺及热退火工艺密切相关，而且存在"耗尽"现象。
