Description
Zinc oxide (ZnO) single crystal has attracted much attention due to its potential
application in ultra violet (UV) and blue light-emitting devices. In addition, ZnO
crystal is a promising fast scintillator. It is reported that doped ZnO crystals
exhibited pulse rise-times <100ps and fall times <1ns, which are faster than any
currently available scintillators. However, it is difficult to obtain ZnO bulk
crystal due to its strong polar surfaces and volatilization at higher temperatures.
In the present work, a flux Bridgman technique was developed and doped ZnO bulk
crystals have been grown from a high temperature solution of ZnO-PbF2 system. The
growth defects were characterized and the physical properties were measured.
