Claim 0:
1. A spectrometer, comprising:
a first base substrate;
a second base substrate opposite to the first base substrate;
a detection channel between the first base substrate and the second base substrate and configured to accommodate or pass a liquid to be detected;
a quantum dot light emitting layer on a side of the first base substrate that is close to the second base substrate, and including a plurality of quantum dot light emitting units, wherein 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;
a black matrix on the side of the first base substrate that is close to the second base substrate, and configured to separate the plurality of quantum dot light emitting units; and
a sensor layer, including a plurality of sensors in one-to-one correspondence with the plurality of quantum dot light emitting units,
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.
