Description

technical field [0001] The invention relates to the technical field of nanomaterial transfer, in particular to a composite fluorescent microscope system for nanomaterial transfer. Background technique [0002] Microscope is a tool for people to understand the microscopic world, and plays a pivotal role in daily scientific research in the fields of biomedicine, materials science and geology. With the continuous deepening of research on the shape of materials, the size of materials involved in production and scientific research practice has reached the nanometer level, especially two-dimensional materials represented by graphene, black scale and two-dimensional layered transition metal chalcogenides. Two-dimensional materials refer to materials in which electrons can only move freely on the non-nanoscale in two dimensions, that is, electrons move on a plane. There are many kinds of common two-dimensional materials, such as nano film, superlattice, quantum well and so on. Cur...

Problems solved by technology

However, the traditional dry transfer method requires manual alignment of the substrate to be transferred and the target substrate, and the light reflected on the target substrate needs to pass through the substrate of the transferred material into the observation microscope

Therefore, in the preparation of two-dimensional materials, it is necessary to select the substrate of the transferred material with good light transmission, and the substrate of the transferred material should have sufficient strength and thinner thickness, which will complicate the preparation process of two-dimensional materials. At the same time, the preparation cost of two-dimensional materials is increased

And the color of some two-dimensional materials is very close to the color of the substrate, making it impossible to distinguish
