Claim 15:
16. A fabrication method of a spectrometer, comprising:
forming a black matrix and a quantum dot light emitting layer including a plurality of quantum dot light emitting units on a first base substrate;
forming a sensor layer including a plurality of sensors; and
providing a second base substrate opposite to the first base substrate to form a detection channel between the first base substrate and the second base substrate and configured to accommodate or pass a liquid to be detected,
wherein the quantum dot light emitting layer is on a side of the first base substrate that is close to the second base substrate; the black matrix is on the side of the first base substrate that is close to the second base substrate, and is configured to separate the plurality of quantum dot light emitting units; and the plurality of sensors and the plurality of quantum dot light emitting units are in one-to-one correspondence with each other, and an orthogonal projection of the plurality of quantum dot light emitting units on the first base substrate falls within an orthogonal projection of the detection channel on the first base substrate,
the quantum dot light emitting layer protrudes from a surface of the first base substrate, and protrudes toward the second base substrate, the detection channel in which fluid to be investigated is located is in the second base substrate, and the plurality of sensors are located between the second base substrate and a third base substrate, the third base substrate is opposite to the second base substrate and located on a side of the second base substrate away from the first base substrate, and the sensor layer and the quantum dot light emitting layer are located in a same side of the detection channel.
