Synthesis and properties of nanocrystal BiPO4 in diamagnetic PbO-Bi2O3-B2O3 glass

In this study, we synthesized of BiPO4 nanocrystals in diamagnetic glass (45PbO-45Bi(2)O(3)-8B(2)O(3)-2P(2)O(5)mol %) by melt quenching technique and studied its influence to glass Faraday rotation. The 9 nm irregular BiPO(4)nanocrystals formed in glass and changed glass structure, spectral and properties through the characterization of X-ray diffraction, field Emission scanning electron microscopy, differential scanning calorimetry, UV-Vis optical absorption, Vicker's hardness and Verdet constant etc. The BiPO4-induced local plasmon effect and bigger polarization gave glass improvements on optical cutoff wavelength, Faraday rotation and Vicker's hardness which is very attractive to magneto optical glass devices.
