The influence of microindentation on the electroluminescence of silicon carbide was studied in forward-biased 4H SiC p-i-n junctions. Four spectral regions at approximately 390, 420, 445 and 500 nm initially observed on virgin samples strongly depend

The absorption spectrum of Ce in a YAG based host grown using the glycothermal method was modified using the addition of Mg-Si pairs. Photoluminescence intensity was dramatically improved by increasing the reaction temperature to 315 °C instead of t

We report here the first use of a vertically aligned copper oxide (CuO) nanowire array in an alternating current-driven zinc sulfide (ZnS:Cu)-based powder electroluminescent (ACPEL) device. As a re...

Broad impact may be anticipated when an energy bandgap is varied substantially by a small change in the physical environment. Such possibility has now been discovered by the example of a perovskite structure of KMnF3 in this paper, where photolumines

Ce:YAG/YAG nanophosphors are synthesized using a two-step seed mediated glycothermal process. The need for the proposed process arises from the high sensitivity of Ce3+ to its local environment, the highly defective surfaces of nanoparticles, and inc

An AC-driven powder electroluminescent (EL) device has been achieved by constructing a CuO nanowire-Zn2 GeO4 :Mn phosphor heterogeneous junction. The CuO nanowires enhance the local electric field, resulting in electroluminescence of an oxide-based p

ZnO nanowires have been grown on polycrystalline Zn2GeO4:Mn substrates for the first time using a chemical vapor deposition method. Both Zn and ZnO sources were used to supply Zn vapor in the growth process of ZnO nanowires. The Zn2GeO4:Mn substrates
