摘要：

Thermal imaging materials with high sensitivity and the ability to reflect real-time temperature play an important role in research areas such as biotechnology and electronic engineering. However, the temperature sensitivity and temporal resolution of the current materials are not suitable for the complicated detection situation. In this paper, we introduce a thermal imaging material - SrB4O7:5%Sm2+ - with high temperature sensitivity. Furthermore, by applying a time resolving technique based on an intensified charge-coupled device, the sensitivity and temporal resolution are greatly promoted. The good temperature sensitivity (9.67% K-1 at 533 K), the high spatial resolution (2.7 mu m) and the fast detection time (<1 s) suggest its considerable potential for real-time thermal imaging applications. The results of temperature distribution on a printed circuit board show that the as-prepared material will be greatly beneficial for thermal imaging applications.
