increasing the concentrations and emissions of greenhouse gases makes the weather warmer and affects land uses. carbon dioxide emission is recognized as one of the most important factors in global warming. the objectives of this research were to investigate the amount of co2 emission from soil to atmosphere during the wheat growth under two different tillage and irrigation methods. in this stud...

Defect radiation has been always considered as the most important loss for an emitter based on band gap emission. Here, we propose a novel approach which goes against this conventional wisdom. Based on the resonance effect between the surface plasmon of metal nanoparticles and defect emission, it is possible to convert the useless defect radiation to the useful excitonic emission with a giant e...

We have experimentally verified that the emission of visible light from dye doped polymers can be enhanced with the use of surface plasmon coupling. By matching the plasmon frequency of a thin unpatterned silver film to the emission of a dye doped polymer deposited onto this metal surface, we have observed a eleven-fold enhancement of light emission. By patterning the silver layer, we estimate ...
