Abstract

$CaZrO_3:Tb$ as a new green-emitting phosphor, has been synthesized by solid state reaction. Photoluminescence and cathodoluminescence properties for the phosphor with a Perovskite structure were investigated. The $CaZrO_3:Tb$ phosphor, which has several emission peaks due to energy transfer from $^5D_4$ to $^7F_J(J=6,5,4,3)$ of $Tb^{3+}$ ion, exhibited strong green luminescence with the main emission peak centered at 545 nm. Optimum Tb concentration was 0.02mol%.
