Dependence of Temperature Sensitivity on the Shape of NaYF4:Yb,Er Upconversion Phosphors

Parameters of synthesis are varied to fabricate NaYF 4 :Yb,Er phosphors with expressed upconversion properties when excited at a wavelength of 980 nm. Data from luminescence spectroscopy shows the particles exhibit temperature sensitivity in the range of 240–350 K, allowing temperature to be measure...

Description
Summary:	Parameters of synthesis are varied to fabricate NaYF 4 :Yb,Er phosphors with expressed upconversion properties when excited at a wavelength of 980 nm. Data from luminescence spectroscopy shows the particles exhibit temperature sensitivity in the range of 240–350 K, allowing temperature to be measured ratiometrically.
