Embodiment Construction

[0024] The technical scheme of the present invention is described in detail below:

[0025] A method for preparing a fluorescent layer, comprising the steps of,

[0026] Step 1. Add ZnS:Cu phosphor to the potassium silicate solution with a mass concentration of 0.5-1% and stir thoroughly;

[0027] Step 2, adding a barium nitrate solution with a mass concentration of 0.1-0.3%, and continuing to stir;

[0028] Step 3, drain the mixed solution into a glass vessel with a glass base, and let it settle naturally;

[0029] Step 4. After the phosphor powder is deposited on the glass substrate, it is taken out and dried, and the required phosphor layer can be obtained after it is naturally cooled to normal temperature.

[0030] The volume ratio of the potassium silicate solution to the barium nitrate solution is 10:1-20:1, and the quality of the ZnS:Cu phosphor and the thickness of the phosphor layer are set according to the following formula: ,in m is the mass of the phosphor, ρ...

Abstract

The invention discloses a preparation method of a fluorescent layer. At first, a layer of fluorescent powder is arranged on a glass substrate through a physical settling method. The fluorescent layer can be used in a nuclear battery structure and is arranged between a radioactive source and a photovoltaic semiconductor assembly. The fluorescent layer is used as an intermediate energy change medium during the process that radioactive energy is converted into electric energy, can effectively prevent the photovoltaic semiconductor assembly from being damaged by the radiation from the radioactive source, and thus prolongs the service life of nuclear battery. Solved is the problem that in a conventional nuclear battery, the semiconductor is easily damaged by irradiation because of the radio-voltaic effect. The provided nuclear battery is portable and safe, and can be applied to electronic devices such as monitors, signal receivers, microcontrollers, and the like.

Description

technical field [0001] The invention belongs to the fields of nuclear physics, nuclear energy application and micro energy, and in particular relates to a preparation method of a fluorescent layer. Background technique [0002] In recent years, with the development and improvement of population and living standards, the demand for energy has also increased day by day. However, with the deepening of space exploration and the advancement of high-tech energy technology industries, human beings have also put forward higher requirements for energy. In many fields such as ultra-low power devices and automatic control systems, especially in some places where replacement and maintenance are difficult at present, long-life, efficient and stable energy supply systems have great potential utilization value. Nuclear batteries with advantages such as long life (depending on the half-life of radioactive isotopes), small size, light weight, strong environmental adaptability, wide operating...
