Project summary

Now, in conditions of increasing ecological crisis, UV radiation received on the Earth grow substantially, and as a result there is oppression of growth and reduction of capabilities of plants. It is possible to reduce negative influence of ultra-violet irradiation on biological objects using our original strategy of transformation of a part of UV radiation into biologically useful light.

The purpose of this project is development of a scientific basis of new non-polluting natural technologies for bio-stimulation of plants, to increase their stability to injuring factors of various nature and creation of materials to convert UV radiation into biologically useful light.

Realization of the specified purpose is to be provided by transformation of solar ultra-violet radiation into radiation of certain sub-ranges of the visible light basing on the use of phosphors introduced into polymer materials, glass etc.

Realization of the project is impossible without participation of experts of the technological pisions that have wide experience in the field of material science and earlier were involved in the weapon development; this project will promote their reorientation into peaceful activity.

Within the project it is supposed:

  • To develop a technology to produce phosphor compositions with the specified optimum parameters of UV transformation of radiation into sub-ranges of visible and infra-red light.
  • To develop a technology to produce nano- disperse particles with the average size of 50 nm (instead of now- in- use 5 microns).
  • To polish ways to apply polymer film with phosphors on existing glass covers of hothouses.
  • To get effective spectra for the dependence of biological effects at various objects on the wave length of the transformed irradiation.
  • To reveal plants most responsive to the effect of additional irradiation
  • To estimate stability of plants to the influence of adverse environmental factors under conditions of their additional low-energy irradiation with red light.

The important contribution to work under the project will be made by experts in the field of the nuclear and radiation physics that were earlier involved in the development and tests of nuclear weapons. Their wide experience in realization of experiments in nuclear physics will allow us to study within the project an opportunity of updating properties of phosphors and increases their conversion efficiency in radiation experiments using unique pulse accelerating installations of VNIIEF. With this purpose original measuring techniques will be used that allow us with high accuracy to determine the parameters of radiation loading fields.

The value of this Project is determined by the following:

  • there will be worked out principles and methods to produce phosphors with the specified parameters of UV radiation transformation into visible and IR spectral regions;
  • production of nano-disperse particles of phosphors is of high practical value for reduction (by 10-100 times) of additional costs related to the introduction of active ditives into various materials;
  • development of techniques to apply polymer materials with phosphors onto glass covers of green-houses will allow upgrading the efficiency of the constructed green-houses at the expense of the increased capabilities of plants;
  • clarification of the mechanisms of biostimulating influence of low-energy irradiation of the plants will make it possible to use it specifically for regulation of the production process and upgrading stress- resistance of various kinds of plants.
