Abstract

Yb³⁺/Er³⁺ co doped SrTiO₃ ceramic have been prepared through solid state reaction route and then x-ray diffraction, upconversion photoluminescence properties of the sample are investigated. The variation of upconversion intensities with external temperature exhibits a well-fashioned pattern, which suggests that the ²H _{1 ½} and ⁴S_3⁄2 levels of Er³⁺ ion are thermally coupled. The upconversion mechanism is well explained in terms of phonon-assisted cooperative sensitization. Based on the above upconversion properties the ceramic sample is suggested for near infrared laser based optical imaging and solid state lighting areas.
