We have used spectral hole burning to measure the homogeneous linewidth of the (3)H(6)(1)- (3)F(3)(1) transition of Tm(3+) ions doped into oxyfluoride glass ceramics consisting of nanocrystals of LaF(3) in an aluminosilicate glass matrix. From the magnitude of the hole width in the nanocrystals and its dependence on temperature, we propose that excitation of tunneling modes in the adjacent glassy phase as well as of confined mechanical modes in the nanocrystals is responsible for the broadening.
我们利用光谱烧孔技术测量了掺杂在铝硅酸盐玻璃基体中含有氟化镧纳米晶体的氟氧化物玻璃陶瓷中铥离子（Tm(3+)）的（3）H(6)(1)-（3）F(3)(1)跃迁的均匀线宽。根据纳米晶体中空穴宽度的大小及其对温度的依赖性，我们提出相邻玻璃相中的隧穿模式以及纳米晶体中的受限机械模式的激发是导致线宽展宽的原因。
