Problems solved by technology

But the use of pesticides pollutes the environment and threatens people's health and life safety
In recent years, the method of trapping and killing insects with lights has appeared. Light trapping and killing insects is a physical control method that uses the phototaxis of pests to trap and kill pests. It is an important ecological agricultural technology. This kind of investment is less and the effect is better. It is necessary to set up power lines, which is not very convenient for outdoors, especially in the wild, and the cost will also increase significantly, while the luminescent material does not need to use electric energy, which can solve some inconvenient problems in the process of trapping and killing insects with lights

Abstract

The invention discloses a synthesis method of luminescent material for an insect-killing trapping lamp which has the advantage of good powder flowability, high insect-killing and trapping efficiency and no environmental pollution. The method comprises the following steps: calculating proportioning according to the chemical formula (A1-x-yByCex)5(PO3)3C2-yD, weighting raw materials, taking fluxing agent, mixing the materials evenly, placing the materials in a corundum crucible, placing the crucible in a furnace with oxidizing atmosphere to ignite, crushing the obtained material, sieving, using diluted nitric acid solution to wash the material to neutral, performing suction filtration and drying powder, placing the powder in reducing atmosphere to ignite and finally sieving and grading to obtain the finished product. The luminescent material of the invention solves the problem that light source is inconvenient to use in some occasions in the traditional method of using light to trap and kill insects; in addition, the luminescent material for insect-killing trapping lamp can be used to trap and kill insects owning to the insect taxis to colors so as to kill insects effectively, save cost and increase the efficiency; and the environmental pollution caused by using a large number of pesticides can be avoided so as to avoid the poisoning of human and livestock.

Description

technical field [0001] The invention relates to a method for synthesizing a luminescent material, in particular to a method for synthesizing a luminescent material for trapping and killing insect lamps. Background technique [0002] In agriculture, forestry, and animal husbandry, in order to reduce the damage caused by pests to crops, people, and livestock, people use a large amount of pesticides to kill them. However, the use of pesticides pollutes the environment and threatens human health and life safety. In recent years, the method of trapping and killing insects with lights has appeared. Light trapping and killing insects is a physical control method that uses the phototaxis of pests to trap and kill pests. It is an important ecological agricultural technology. This kind of investment is less and the effect is better. Electric lines need to be erected, which is inconvenient for outdoors, especially in the wild, and the cost is also greatly increased, while luminescent ...
