We propose a modified MgO protective layer for alternating current plasma display panels. The modified MgO protective layer of the panel tested here has a structure that incorporates silica-coated Au nanorods (NRs), leading to localized surface plasmon resonance (LSPR) in the near-infrared (IR) region. The silica-coated Au NRs were synthesized by a simple chemical method and inserted into an MgO protective layer using an air-spray method. The operating voltage of the proposed structure was decreased by 10 V. The luminance and luminous efficacy of the test panel part with the silica-coated Au NRs both increased by about 15%. According to the measured results of the IR response time, the sustain discharge time lag was reduced. In addition, by inserting the silica-coated Au NRs into the MgO protective layer, a decrease of the IR emission proceeding from the plasma discharge was acquired. Finally, we investigated the LSPR effect of the silica-coated Au NRs in a simulation with a finite-difference time domain method.
我们提出了一种用于交流等离子体显示面板的改性氧化镁保护层。此处测试的面板的改性氧化镁保护层具有一种包含二氧化硅包覆金纳米棒（NRs）的结构，导致在近红外（IR）区域产生局域表面等离子体共振（LSPR）。二氧化硅包覆的金纳米棒通过一种简单的化学方法合成，并使用空气喷涂法插入到氧化镁保护层中。所提出结构的工作电压降低了10V。带有二氧化硅包覆金纳米棒的测试面板部分的亮度和发光效率均提高了约15%。根据红外响应时间的测量结果，维持放电时间延迟减小。此外，通过将二氧化硅包覆的金纳米棒插入氧化镁保护层，获得了等离子体放电产生的红外发射的减少。最后，我们用有限时域差分法在模拟中研究了二氧化硅包覆金纳米棒的LSPR效应。
