We demonstrated microfluidic electrogenerated chemiluminescence cells incorporated with titanium dioxide nanoparticles (TiO 2 NPs). SU-8-based microchannels were fabricated on a fluorine doped tin oxide cathodes-patterned glass substrate. TiO 2 NPs were coated on the cathodes as an electron injection layer. The enclosed microchannels were achieved by a direct bonding of the SU-8 surface to an indium tin oxide anode-patterned polyethylene terephthalate film via vacuum ultraviolet treatment. A tris(2,2′-bipyridine)ruthenium(II) solution was used as an emitter. The proposed device exhibited a maximum luminance of 93.5 cd m −2 at 3.3 V, which is 1.45 times higher than that of device without TiO 2 NPs.

掺有二氧化钛纳米粒子的微流电化学发光细胞的制备，以提高发光性能

我们展示了微流体电生化学发光细胞与二氧化钛纳米粒子（TiO 2 NPs）合并。基于SU-8的微通道是在掺氟氧化锡阴极图案的玻璃基板上制造的。TiO 2 NPs作为电子注入层涂覆在阴极上。封闭的微通道是通过真空紫外处理将SU-8表面直接粘合到氧化铟锡阳极构图的聚对苯二甲酸乙二醇酯薄膜上而实现的。使用三（2,2'-联吡啶）钌（II）溶液作为发射极。所提出的器件在3.3 V电压下的最大亮度为93.5 cd m -2，是没有TiO 2 NPs的器件的1.45倍。
