Substrate temperature dependence of structure and optical properties of ZnTiO₃:Er³⁺/Yb³⁺ thin films synthesized by pulsed laser deposition.

ABSTRACT: ZnTiO₃:Er³⁺,Yb³⁺ thin film phosphors were successfully deposited by pulsed laser deposition (PLD) at different substrate temperatures. The distribution of the ions in the films was investigated and the chemical analysis showed that the doping ions were homogeneously distributed in the thin films. The optical response of the phosphors revealed that the reflectance percentages of the ZnTiO₃:Er³⁺,Yb³⁺ vary with the silicon substrate temperature due to the differences in the thickness and morphological roughness of the thin films. Under 980 nm diode laser excitation, the ZnTiO₃:Er³⁺,Yb³⁺ film phosphors displayed up-conversion emission from the Er³⁺ electronic transitions, with violet,
