VUV-UV-vis photoluminescence, X-ray radioluminescence and energy transfer dynamics of Ce³⁺ and Eu²⁺ in Sr₂MgSi₂O₇

Ce³⁺ and Eu²⁺ doped and Ce³⁺-Eu²⁺ co-doped Sr₂MgSi₂O₇ phosphors are prepared via a high-temperature solid-state reaction technique. The synchrotron radiation vacuum ultraviolet-ultraviolet (VUV-UV) excitation and ultraviolet-visible (UV-vis) emission spectra of...

Interactions between Diffuse Light and Cucumber (Cucumis sativus L.) Canopy Structure, Simulations of Light Interception in Virtual Canopies

Plant photosynthesis and biomass production are associated with the amount of intercepted light, especially the light distribution inside the canopy. Three virtual canopies (n = 80, 3.25 plants/m2) were constructed based on average leaf size of the digitized plant structures: ‘small leaf’ (98.1 cm2), ‘medium leaf’ (163.0 cm2) and ‘big leaf’ (241...
