Spectroscopic in-depths of upconverting NaZr(PO) phosphors for LIR-based thermometry.

This study employed solid-state synthesis to develop the green emitting Er-Yb:NaZr(PO), NASICON material. Using Rietveld refinement, the crystallographic variables of the synthesized phosphors were precisely calculated. The upconverting phenomenon was seen with naked eye when exposed to 980 nm laser radiation.

Temperature sensing using bulk and nanoparticles of CaErYbMoOphosphor.

Optical temperature sensing is widely realized by using upconversion (UC) emission in lanthanide-doped phosphors. There are various parameters that are responsible for UC intensity of the phosphor like particle shape and size, type of symmetry that exist at the site position, distribution of lanthanide ions in the phosphor, and so on. However, a comparative study of the bulk and nanostructure on the temperature sensing ability of such phosphor is rare.

Tailoring of upconversion luminescence of Alengineered titanate phosphor for non-invasive thermometry.

The ability of rare-earth-doped ferroelectric oxides to achieve outstanding upconversion (UC) performances under NIR irradiation despite possessing intrinsic electric properties drives researchers all over the globe to work in this field. The structural and spectroscopic characteristics of the BiTiOphosphor integrated with Er, Yb, and Alhave been thoroughly investigated in this study. The considerable increase in UC emission ∼three times caused by the addition of Alions has been observed and discussed.
