Multifunctional Fe 3 O 4 @Gd 2 O 3 :Tb 3+ @SiOx nanoparticles were successfully synthesized by co-precipitation and polyol methods. The synthesized nanoparticles were composed by cubic phase as core of Fe 3 O 4 and Gd 2 O 3 :Tb 3+ and the shell of amorphous SiOx. The composites exhibited a spherical shape with a diameter of 10-15 nm and highly uniform dispersion. They showed not only excellent fluorescence under excitation at a wavelength of 278 nm, but also strong magnetic responsiveness (M S = 24.040 emu g −1 ). The results of magnetic resonance imaging in vitro (r 1 = 6.00 mm −1 s −1 , r 2 = 63.95 mm −1 s −1 ) showed that the samples could be used as T 1 -positive and T 2 -negative contrast agents. In addition, it was found that Fe 3 O 4 @Gd 2 O 3 :Tb 3+ @SiOx attains hyperthermia temperature (43 • C) in 90 s under the alternating current magnetic field, and their specific absorption rate (229.9 w g −1 ) was higher than that of Fe 3 O 4 (183.92 w g −1 ). Hence, the multifunctional nanoparticle could be used for the diagnosis and therapy of cancer.

“…Many researchers have introduced the use of Novel bifunctional Nd:YAG/Fe 3 O 4 nanocomposite as nanothermometer/ nanoheater for potential biomedical applications E M Tejeda 1 , M Arámburo 2 , E Vargas 2 , O E Contreras 1 and G A Hirata 1 magnetite NPs in hyperthermia treatments, their work relies on the close-to-non toxicity levels of these NPs, and its excellent superparamagnetic character [8][9][10][11]. While some report the usage of this material in combination with phosphors [1,[12][13][14][15] mainly for tagging, bioimaging purposes, drugdelivery [14,16,17]; only a few report these materials as heater/optical thermometer nanocomposite [18][19][20].…”

This work reports a novel bifunctional nanocomposite made of infrared-emitting nanophosphors and superparamagnetic nanoparticles, which simultaneously provides heating and temperature sensing at the nanoscale level. Highly luminescent Y3Al5O12:Nd3+ nanophosphors were synthesised by using a sol–gel route and were subsequently mixed with superparamagnetic nanoparticles producing a core–shell structure, which displayed superparamagnetic and fluorescent properties in the same nanostructured system. As a result, this bifunctional nanocomposite showed two essential characteristics: (i) it increased in temperature up to 57 °C upon exposure to an alternating magnetic field of sufficient strength and frequency, and (ii) its temperature could be optically sensed by monitoring the infrared luminescence emitted from the YAG:Nd nanophosphor. Our experiments revealed that the YAG:Nd/Fe3O4@SiO2 nanocomposite possesses excellent luminescence and superparamagnetic properties; both physical properties are driven in a non-contact manner making it appropriate for sensing local heating and temperature of cells, and also suitable to be used in medical treatments with minimal invasiveness.
