正確な低温ルミネッセンス測定のための既知の温度で熱的に平衡化サンプルのための簡単​​なデュワー/クライオスタット

A simple liquid nitrogen Dewar/cryostat apparatus comprised of a small fused silica optical Dewar, a thermocouple, and a charge-coupled device (CCD) spectrograph are described. The experiments for which this Dewar/cryostat is designed require fast sample loading, freezing, and alignment, accurate and stable sample temperatures, and small size/portability.
