我们使用罗丹明6G （RH6G）的低功率激光器（在514和633 nm处0.5 mW）在干燥的银胶体上在140至350 K的广泛温度范围内系统地测量了反Stokes/Stokes （aS/S）比。我们表明，温度扫描允许从共振效应和加热中独立提取对反斯托克斯/斯托克斯比的贡献，从而将问题的两个方面解耦。
We make systematic measurements of the anti-Stokes/Stokes (aS/S) ratios using low power lasers (0.5 mW at 514 and 633 nm) of rhodamine 6G (RH6G) on dried silver colloids over a wide range of temperatures from 140 to 350 K. We show that a scan in temperature allows the extraction of the contributions to the anti-Stokes/Stokes ratio from resonance effects and heating independently, thus decoupling the two aspects of the problem.
