Abstract: (1850 Views)
Recently, lanthanide nano-emitters have found numerous applications in biotechnology and biomedical engineering due to their remarkable properties. Upconversion mechanism, zero background emission, large anti-Stokes shift and being in the transmission window of living tissues are among these features. In this work, temperature-dependence of lanthanide nano-emitters is investigated. For this purpose, nano-emitters of : , are used in which is the host matrix. In these upconversion nano-emitters, ion acts as sensitizer and as activator which both are doped in the host material. Subsequently, these nano-emitters are doped in dimethylsiloxane elastomer for fabrication of nanocomposite films. Temperature of the film is increased in a water container, therefore the temperature-dependence of the emission of these nano-emitting composite is studied.
