Abstract:
This study investigates in detail the laser-mediated upconversion emission and temperature-sensing capability of (Ca 0.99− a Yb 0.01 Er a )TiO 3 . Samples were prepared at different concentrations to observe the effect of erbium on upconversion while increasing its concentration and keeping all the other parameters constant. Doping is a widespread technological process which involves incorporating an element called a dopant in a lower ratio to the host lattice to derive hybrid materials with desired properties. The (Ca 0.99− a Yb 0.01 Er a )TiO 3 perovskite nanoparticles were synthesized via a sol–gel technique. The frequency upconversion was performed using a 980 nm laser diode excitation source. X-ray diffractometry (XRD) confirmed that the synthesized samples are crystalline in nature and have an orthorhombic structure. The temperature-sensing ability was examined using the fluorescence intensity ratio (FIR) algorithm of two emission bands ( 2 H 11/2 → 4 I 15/2 and 4 S 3/2 → 4 I 15/2 ) of the Er 3+ ion. Temperature-dependent upconversion luminescence is observed over a broad temperature range of 298–623 K. The maximum sensor sensitivity obtained is 6.71 × 10 −3 K −1 at 110°.
