Outline of Final Research Achievements |
This research project is aimed for developing photo-thermal microscopy method toward real time detection. The proposed method uses diamond nitrogen vacancy (NV) centers as nanoscale thermometers. NV centers have electron spins and can sense the local temperature at nanoscale. We have developed an optically detected electron spin measurement system and measured NV’s spin property in a pulsed electron spin resonance method. With this system, we have analyzed the spin properties of nanodiamond NV centers and the effect of surface termination. The photo-thermal image sensors need high-density nanodiamond arrays. We realized first prototype of such arrays (tens of micrometers in size) by a precise ink-jet technique.
