초록

The effect of $Y^{3+}$ addition to $SrTiO_3:Pr^{3+}$ on the photoluminescence and cathodoluminescence was studied. We discovered that light emitting levels of $Pr^{3+}$ vary by addition of $Y^{3+}$. In $(Sr_{1-x}Y_x)TiO_3:Pr^{3+}$, both the green and red emission are discovered while the red emission prevails in $Sr(Ti_{1-x}Y_x)O_3:Pr^{3+}$ . $Sr(Ti_{1-x}Y_x)O_3:Pr^{3+}$ shows enhancement of red emission by two kinds of enhancement process.
