Chemical decomposition of CdTe and CdBr2 dopants in KBr

Chemical decomposition of CdTe and CdBr 2 dopants in KBr single crystals was confirmed by optical absorption, photoluminescence and electron paramagnetic resonance (EPR). An intense UV-emission band observed at 393 nm is assigned to optical response of Cadmium impurities; this intense UV emission ba...

Description
Summary:Chemical decomposition of CdTe and CdBr 2 dopants in KBr single crystals was confirmed by optical absorption, photoluminescence and electron paramagnetic resonance (EPR). An intense UV-emission band observed at 393 nm is assigned to optical response of Cadmium impurities; this intense UV emission band can be useful in light-emitting devices and optoelectronic applications.
