Abstract

{Cr}^{3 +} / {Yb}^{3 +}

codoped

Y_{3} {Al}_{5} O_{12}

(i.e., YAG) thin films are prepared by pulsed laser deposition. The films are characterized by X-ray diffraction, atomic force microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and photoluminescence spectra. Excitation at 446 or 587 nm, a broadband emission in the range of 610–800 nm, and an intense near-infrared at 1030 nm are obtained, showing cooperative energy transfer from

{Yb}^{3 +}

ions in the

{Cr}^{3 +} / {Yb}^{3 +}

codoped YAG thin films; energy transfer efficiency is 71%. The YAG films may have potential application to enhance the efficiency of silicon solar cells.
