Abstract

The invention discloses a light conversion agent, a preparation method of the light conversion agent, a light conversion master batch, a preparation method of the light conversion master batch, a light conversion film and a preparation method of the light conversion film. The light conversion agent has a general formula of MO.xAl2O3: Mn, TM. The light conversion master batch comprises the light conversion agent and organic carriers. The light conversion film comprises the light conversion agent and light conversion agent carriers. The preparation method of the light conversion agent has simple processes. The light conversion agent comprises uniformly dispersed ingredients, has a cost greatly lower than that of the traditional light conversion agent, good stability and an emission spectrum matching with a plant photosynthesis spectrum, improves absorption and conversion efficiency of sunlight and improves a matching degree.

Description

technical field [0001] The invention relates to a light conversion agent and a preparation method thereof, a light conversion masterbatch and a preparation method thereof. Background technique [0002] The light conversion film is a film that realizes light conversion by adding a light conversion agent. It can convert ultraviolet light that is harmful to plant growth into blue-violet and red-orange light that is useful to crops, or convert green and red light that plants do not absorb. The yellow-green light is converted into red light. That is, by changing the light quality that passes through the light conversion film, it can promote the absorption of nitrogen, phosphorus, potassium, zinc and other nutrients by plants, increase the content of photosynthesis products in leaves, promote crop growth, and at the same time play a role in reducing pests and diseases . [0003] After nearly 20 years of rapid development, the light-changing agent has developed into two systems: ...
