정확한 극저온 발광 측정을위한 알려진 온도에서 열적으로 평형화 샘플에 대한 간단한 듀어 /의 저온

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.
