【摘要】 运用晶格动力学观点推导了热导率与积分拉曼散射强度的关系,测量了Nd:YVO4(简称NYV)和Nd:GdVO4(简称NGV)不同配置下的高温拉曼光谱和其a、c向的热导率,理论与实验非常吻合。更多还原

【Abstract】 Based on the lattice dynamics theory,we got a correlation between the thermal conductivity and the Raman scattering integrated intensity.The Raman spectra and thermal conductivities along a-direction and c-direction of NGV and NYV were measured,respectively.The results are agreement with the correlation.更多还原
