摘要

The electrical, thermal, optical, and morphological properties of CUO doped Bi2O3-B2O3-BaO-ZnO glasses were studied as a PbO-free, low firing transparent dielectric layer for plasma display panels (PDP). CuO improved the transmittance of Bi2O3-B2O3-BaO-ZnO by up to 84% in the visible region, eliminating a yellowish color typical of Bi2O3-B2O3-BaO-ZnO. A slight absorption within the near infrared (NIR) region was also observed. The glass transition temperature (T,), thermal coefficient of expansion (TCE), and root-mean square (rms) roughness of 0.005 wt% CuO doped Bi2O3-B2O3-BaO-ZnO were found to be 455 degrees C, 81.4 x 10(-7)/K, respectively, and 162 +/- 14 angstrom, which satisfied the requirements for a transparent dielectric layer for PDP application.
