Abstract

The invention discloses a light-blind organic ultraviolet detection device based on rare earth complex, and relates to an organic ultraviolet detection device, which belongs to the technical field of a photovoltaic detector. The organic ultraviolet detector comprises a transparent glass substrate (1), a transparent electrode (2), an organic layer (3) and a metal electrode (4). The transparent electrode (2), the organic layer (3) and the metal electrode (4) are sequentially prepared on the transparent glass substrate (1). The organic layer is made of the mixture of 3 dibenzoylmethane 4,7- diphenyl-1,10-phenanthroline europium and [6.6]- phenyl-C61-methyl butyrate, mixture of 3 dibenzoylmethane 4,7- diphenyl-1,10- phenanthroline terbium and [6.6]- phenyl-C61-methyl butyrate or mixture of 3 dibenzoylmethane 1,10-phenanthroline europium and [6.6]- phenyl-C61-methyl butyrate, and the mass proportion of the mixture is 1:2 to 2:1. The preparation process is simple, and the sensitivity of the light-blind organic ultraviolet detection device is high.

Description

technical field [0001] The invention relates to an organic ultraviolet detection device, which belongs to the technical field of photoelectric detectors. Background technique [0002] The wavelength range of ultraviolet light is 100-400 nm, which is divided into two sections. The wavelength of 100-200 nm is called the vacuum ultraviolet region. The light in the vacuum ultraviolet band is absorbed by the atomic or molecular oxygen and nitrogen in the atmosphere, and can hardly reach the surface of the earth. The wavelength of 200-400 nm is called the near-ultraviolet region. The light in this band has a certain distribution on the surface of the earth, and its high energy has a certain impact on the growth and survival of animals and plants. Ultraviolet light radiated by the sun and artificially produced ultraviolet light are all harmful to human health. Long-term exposure can lead to cataracts, skin cancer and other diseases. Therefore, the monitoring of ultraviolet light ...
