    Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

    Sammanfattning : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. LÄS MER
