Abstract

In this paper, reflectance and the dielectric characteristics for $P_2O_5$-ZnO-BaO system and $SiO_2-ZnO-B_2O_3$ system have been investigated as a function of contents of $TiO_2$. The reflectance was decreased with increasing the contents of $TiO_2$ contents, and the reflectance of $P_2O_5$-ZnO-BaO system was lowered than that of $SiO_2-ZnO-B_2O_3$ system. The dielectric constant of $P_2O_5$-ZnO-BaO system was higher than $SiO_2-ZnO-B_2O_3$ system, and the dielectric constant in the both system was increased with increasing of $TiO_2$ contents. This can explained as the space charge effects. These results are could be applied to the lower dielectrics layer of PDP required high reflective ratio and breakdown strength.

본 논문에서는 $SiO_2-ZnO-B_2O_3$ 계 및 $P_2O_5$-ZnO-BaO 계의 반사율과 유전특성을 $TiO_2$의 양에 따라 조사하였다. 반사율은 $TiO_2$ 함량이 증가함에 따랴 감소하였다 여기서 $P_2O_5$-ZnO-BaO계는 $SiO_2-ZnO-B_2O_3$ 계보다 더 낮은 반사율을 나타내었으며, 유전상수는 $P_2O_5$-ZnO-BaO 계가 $SiO_2-ZnO-B_2O_3$ 계보다 높았다. 두 계 모두 유전상수는 $TiO_2$의 양에 따라 증가하는 특성을 보였다. 이 결과는 높은 반사율과 항복특성이 요구되는 PDP디스플레이의 후면 유전층에 적용할 수 있을 것으로 생각된다.
