Optical nanothermometer based on the calibration of the Stokes and upconverted green emissions of Er 3+ ions in Y 3 Ga 5 O 12 nano-garnets
SF León-Luis, V Monteseguro… - RSC Advances, 2014 - pubs.rsc.org
The temperature-dependent green luminescence of Y3Ga5O12 nano-garnets doped with
different concentrations of Er3+ ions has been measured from 300 to 850 K and, in more
detail, in the biological range from 292 to 335 K. The green emissions were obtained by
excitation under 488 nm blue or 800 nm near-infrared laser radiations. Both excitations give
rise to bright green luminescence that can be seen by the naked eye, and which can be
associated either with Stokes processes, ie multiphonon relaxations followed by green …
