英文摘要	Resonance Raman spectra of BexZn1-xO alloy materials were studied using 325 nm Laser. The research showed that the Raman spectra of BexZn1-xO alloys presents a dual-mode vibration. Compare BexZn1-xO alloy with ZnO single crystal, the A(1) (LO) phonon vibration mode of BexZn1-xO alloy moved to the larger wave number direction. The position of A(1) (LO) phonon vibration modes of Be0.08Zn0.92O and Be0.12Zn0.88O was 580 cm(-1) and 582 cm(-1), respectively. In addition, the temperature-dependent Raman spectroscopy was employed for Be0.12Zn0.88O, and the phonon mode frequency shift with temperature was studied in detail. Finally, the stability of the polar and nonpolar BexZn1-xO alloy materials was studied using resonance Raman spectroscopy. The results showed that the A(1) (LO) phonon mode frequency of polar BexZn1-xO alloy remained in the same position, while the nonpolar BexZn1-xO alloys moved nearly 3.5 cm(-1) to larger direction after being placed in the air for two years. The reason may be that the stability of the nonpolar BexZn1-xO alloy is relatively poor upon interaction with molecule such as H2O, O-2 in the air.
