1. A chiral zinc borate Zn2(OH)BO3, which exhibits nonlinear optical, photoluminescent and photoelectronic properties, has been successfully prepared through a hydrothermal reaction. The structure of the compound has a ZnO matrix and the electronic structure of the compound can be regarded as that for ZnO modified by the presence of B atoms. The luminescence properties of Zn2(OH)BO3 were characterized by excitation and emission spectra. Photovoltage signals were observed for the as-synthesized compound and for samples calcined at various temperatures by surface photovoltage spectroscopy (SPS) and field-induced surface photovoltage spectroscopy (FISPS). The results show that Zn2(OH)BO3 has photoelectric transformation ability. Either thermal treatment or application of an external electric field enhances the photovoltage responses of the compound to a considerable extent.

2 A highly intense green-emitting phosphor BaY2Si2Al2O2N5 : Eu2+ (BYN : Eu2+) peaking at 511 nm was synthesized by a solid state reaction. The structure refinement, luminescence properties of BYN : Eu2+ phosphors as well as their thermal quenching and the fabrication of white-light-emitting diodes (W-LEDs) were firstly investigated. By partially substituting Ba by Sr, namely (Ba,Sr) Y2Si2Al2O2N5 : Eu2+ (BSYN : Eu2+), the emission peak was shifted to 565 nm, giving a yelloworange color, due to the splitting of the 5d energy level. By utilizing a mixture of blue-emitting BaMgAl10O17 : Eu2+, green-emitting BYN : Eu2+ and red-emitting CaAlSiN3 : Eu2+ phosphors as light converters, an intense white GaN-based n-UV-LED (380 nm) was fabricated to a exhibit good color-rendering index Ra of 84.5 at a correlated color temperature of 5089 K and CIE coordinates of (0.3425, 0.3478). Based on these results, we are currently evaluating the potential application of BYN : Eu2+ as a green-emitting near-UV convertible phosphor.
