preparation example Construction

[0065] The second embodiment of the present disclosure provides a preparation method of an ultraviolet sensor, such as image 3 As shown, the method includes the following steps:

[0066] S101 : preparing photochromic ink 3 .

[0067] For the above step S101, preparing the photochromic ink 3 includes: disposing a certain volume of an aqueous solution of the photochromic polyoxometalate and an aqueous solution of the electron donor; mixing the aqueous solution of the photochromic polyoxometalate and the electron donor The aqueous solutions are mixed so that the electron donors reduce the photochromic polyoxometalates stepwise under certain conditions. Photochromic polyoxometalates can be reduced in multiple steps under the conditions of electron donors and UV light irradiation, resulting in a series of multivalent intermediate products, that is, photochromic polyoxometalates with different colors. It is directly displayed, so that the photochromic ink 3 has the characteristic...

Abstract

Embodiments of the present disclosure provide an ultraviolet sensor, a smart device, and a preparation method. The ultraviolet sensor includes a base, on which at least one identification area is provided, each identification area is provided with a mark made of photochromic ink, and covers different Covering for UV blocking capabilities. According to the color of photochromic ink in different identification areas, users can obtain the intensity of ultraviolet radiation in the current environment with the naked eye, and protect themselves according to their own conditions, in order to avoid high-intensity ultraviolet radiation, by using the photochromic ink on the ultraviolet sensor The characteristics of the ink enable users to monitor the intensity of ultraviolet radiation in daily life in real time, so as to monitor the intensity of ultraviolet radiation in their environment anytime and anywhere, and send out protection reminders in time when the intensity is too high. At the same time, they can adjust the photochromic The composition ratio of the ink or the number of layers or thickness of the covering realizes the customized design for different groups of people.

Description

technical field [0001] The present disclosure relates to an ultraviolet sensor, an intelligent device and a preparation method. Background technique [0002] It is well known that excessive ultraviolet radiation can cause great harm to the human body. UVR (Ultraviolet Ray) includes UVA (wavelength 315–400nm), UVB (wavelength 280–315nm) and UVC (wavelength 100– 280nm), the effect of each band on the human body is very different, in which the atmosphere filters out most of the UVB and all UVC in the sunlight, so the UVR reaching the earth's surface mainly includes UVA and UVB, but UVA and UVB The damage of ultraviolet rays to the human body still exists, especially for people who are sensitive to ultraviolet rays. However, in the prior art, there is no product capable of prompting the user of the ultraviolet intensity in a timely and portable manner. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned technical problems existing in the prior art, the present d...
