NV- center energy level diagram showing how preferential shelving of ms=\u00b11 excited states (3E) into dark metastable state (1A) gives rise to typical electron spin resonance (ESR) spectrum. b. Fluorescence of two NV- centers in presence of a static magnetic field as function of applied microwave frequency. Splitting of two dips (2\u0394\u03c9A,B) is given by projecting incident magnetic field on magnetic moment of the NV- center (2g\u03bcA,B\uf09fB). Contrast of each dip has inverted Lorentzian shape with minimum line width limited by dephasing time due to environment (T2*). c. Illustration of NV- centers in static magnetic field, each having field splitting frequencies corresponding to their uniquely oriented magnetic moments relative to magnetic field. To measure ESR spectra across a wide field of view, average fluorescence intensity is measured across hundreds of diffraction-limited sites (dotted circle) while microwave frequencies are swept. d. Schematic diagram of method for resolving a switchable emitter by taking difference between two images where a uniquely addressed emitter is and is not dimmed by resonant microwave excitation, I(\u03a9ZFS\u00b1\u0394\u03c9) and I(\u03a9o), respectively.<\/p>\n"},"alt_text":"","media_type":"image","mime_type":"image\/jpeg","media_details":{"width":2186,"height":1353,"file":"2013\/07\/chen_nanodiamonds_01.jpg","sizes":{"thumbnail":{"file":"chen_nanodiamonds_01-150x150.jpg","width":150,"height":150,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01-150x150.jpg"},"medium":{"file":"chen_nanodiamonds_01-300x185.jpg","width":300,"height":185,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01-300x185.jpg"},"large":{"file":"chen_nanodiamonds_01-1024x633.jpg","width":1024,"height":633,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01-1024x633.jpg"},"post-thumbnail":{"file":"chen_nanodiamonds_01-150x150.jpg","width":150,"height":150,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01-150x150.jpg"},"abstract-thumb":{"file":"chen_nanodiamonds_01-220x136.jpg","width":220,"height":136,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01-220x136.jpg"},"full":{"file":"chen_nanodiamonds_01.jpg","width":2186,"height":1353,"mime_type":"image\/jpeg","source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01.jpg"}},"image_meta":{"aperture":0,"credit":"","camera":"","caption":"","created_timestamp":0,"copyright":"","focal_length":0,"iso":0,"shutter_speed":0,"title":""}},"post":1573,"source_url":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-content\/blogs.dir\/22\/files\/2013\/07\/chen_nanodiamonds_01.jpg","_links":{"self":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-json\/wp\/v2\/media\/1575"}],"collection":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-json\/wp\/v2\/media"}],"about":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-json\/wp\/v2\/types\/attachment"}],"author":[{"embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-json\/wp\/v2\/users\/370"}],"replies":[{"embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2013\/wp-json\/wp\/v2\/comments?post=1575"}]}}
