Near-infrared photodetectors for non-destructive detection of fruits (6 units)

Project description:

In the practical application, the measurements of the NIR reflection or absorption of the fruits often involves many errors due to the influence of the background light during the day. It is of practical interest that such measurements can be done using visible blind NIR photodetectors during the day, so as to minimizing the possible measurement errors by the ambient light. The students will study the device physics and fabrication of a dual-mode organic NIR photodetector. This FYP project comprises two components: (1) understanding the photoresponse of the NIR/visible dual-mode organic NIR photodetectors, and (2) application of NIR photodetectors, e.g., non-destructive detection of sugar content in fruits.

Capacity: 1-2 students
