Fig. 7. For the housing of the quantum dot light source measurement, black coloration was chosen for the top and bottom plates. This is done to minimize light reflection and the influence of environmental light when measuring the quantum dot light source by painting the exterior of the housing in black tones. Additionally, when closing the housing, the fine structures come into contact with a portion of the sample pad, creating a sealed space within the fine structures, which may prevent the capillary effect from occurring smoothly. To address this, two supply channels are used to control the flow rate and facilitate sequential reactions.
