Zn1-xMgxO crystals with nanostructures were grown on a-plane sapphire substrates using mist chemical vapor deposition (mist-CVD) and exhibited random lasing behavior under high excitation conditions, with tunability in the wavelength range.
Zn1-x Mg x O crystals with nanostructures were grown on a-plane sapphire substrates by mist chemical vapor deposition (mist-CVD). The grown Zn1-x Mg x O crystals had a wurtzite crystalline, and their room-temperature photoluminescence peaks of them varied from approximately 355.5 to 377.9 nm depending on the composition of magnesium. Under high excitation conditions using a Nd:YAG pulse laser, random lasing behaviors were obtained from Zn1-x Mg x O crystals, and the tuning in the wavelength range of these random lasing was demonstrated. These results suggest that the mist-CVD crystal growth on a-plane sapphire substrates is useful for the growth of Zn1-x Mg x O crystals exhibiting random lasing.
