We report the novel photoresponse of nanodevices made from azafullerene (C59N)-encapsulated single-walled carbon nanotubes (C59[email protected]), so called peapods. The photoconducting properties of a C59[email protected] are measured over a temperature range of 10 to 300 K under a field-effect transistor configuration. It is found that the photosensitivity of C59[email protected] depends very sensitively on the temperature, making them an attractive candidate as a component of nanothermometers covering a wide temperature range. Our results indicate that it is possible to read the temperature by monitoring the optoelectronics signal of C59[email protected] In particular, sensing low temperatures would become more convenient and easy by giving a simple light pulse.
