Abstract
The invention discloses a photoelectric device and an electronic device using the photoelectric device. The optoelectronic device includes a photosensitive element, an insulating layer and a quantum dot array layer. The quantum dot array layer is used to process the incident light into multiple light rays containing different optical information, the photosensitive element is used to convert the optical information into electrical signals, and the insulating layer is arranged between the photosensitive element and the quantum dot array layer to avoid quantum The dot array layer affects the electrical properties of the photosensitive element. In the present invention, the quantum dot array layer is directly arranged on the surface of the insulating layer, so that the light emitted by different quantum dot units is not easy to be mixed, which is beneficial to improving the sensitivity of the photoelectric device and the measurement accuracy of electronic equipment using the photoelectric device.
Description
technical field [0001] The invention relates to the field of optoelectronic technology, in particular to an optoelectronic device and an electronic device using the optoelectronic device. Background technique [0002] A spectroscopic instrument is a device used to study and analyze the spectrum of a substance. The spectroscopic technology uses the characteristics of light absorption, reflection and scattering inside the tested sample to detect the parameters of the sample. The two key steps of using a spectrometer to measure light are (1) decomposing light into different wavelength bands of light; (2) converting light information into electrical signals. [0003] At present, gratings are widely used to decompose light, so that the light of different wavelengths is separated from each other in space, and then irradiated on the photoelectric response structure at different spatial positions to realize the transformation of optical information into electrical signals. [0004]...
