Studies have shown that increasing the granularity of energy consumption information in buildings could facilitate achieving energy saving objectives. Lighting systems in buildings are one of the main consumers of electricity with a share of approximately (direct and indirect) 23 percent of the total electricity in the US. Direct monitoring of lighting systems is not feasible due to challenges for...
A red phosphor CaAl12O19: Mn4+ was prepared utilizing the redox of metal nitrates and urea by combustion synthesis with ignition temperature of 700°C. This phosphor can be used in white LED. The shape and surface morphology of the phosphor were controlled by changing the dosage of ammonium nitrate (NH4NO3). The samples were characterized with x-ray diffraction (XRD), scanning electron microscopy (SEM)...
