Photoluminescence, and optically stimulated luminescence in ZnB2X4 (B; Li,Na,K: X; Cl,Br) compounds doped with Cu+ or Ag+ were studied. Double humped emission bands attributable to the activators were observed in all the samples. The observed photoluminescence of Cu+ and Ag+ could be identified with 3d94s1↔3d10 and 4d95s1↔5d10 transitions respectively. The longer wavelength band (400–500 nm range)...
The dosimetric phosphors Li3PO4:M (M = Tb, Cu) were produced by modified solid-state method. The structural and morphological characterization was carried out through X-ray diffraction (XRD) and scanning electron microscope (SEM). Additionally, the photoluminescence (PL), thermoluminescence (TL) and optically stimulated luminescence (OSL) properties of powder Li3PO4 doped with Tb and Cu were studied...
Electric vehicles (EVs) are expected to play an important role in sustainable mobility thanks to the efficient energy utilization and zero-emission when in use. The battery has a great impact on the performance of electric vehicles, basically determining the driving range. As a consequence, the choice of the battery technology and its effective utilization is of paramount importance. Li-ion chemistry...
There is currently a trend in the automotive industry to replace combustion engines with electric motors or a combination of an electric motor and a combustion engine, thereby substantially reducing the environmental impact of automobiles by reducing or completely eliminating car emissions. In this paper various strategies for positioning of smoke sensor within the battery pack assembly for smoke...
Electrical Safety is the most important factor to be considered while circuit design for any EV modules. EVs contain very high power battery of around 200Ah that can be very devastating and extremely hazardous in case of any abnormalities. Hence Safety protection in the electrical circuits is the very critical and requires 100% accuracy. Electric vehicles contain many complicated circuitries. These...
