The structures of zinc oxide and La doped ZnO were characterized through X-ray powder diffraction (XRD), transmission electron microscope (TEM), Uv-vis diffuse spectrum (UV – vis DRS).
For Nanometer ZnO, doping can not only modify its crystalline structure but also the energy level structure, further to influence its many properties [3-4].
Structure and crystallinity of the ZnO and L-ZnO samples were characterized by powder X-ray diffraction (XRD) on a D8 Advance Bruker X-ray diffractometer with monochromatized Cu KR radiation (λ=l.5416 Å).

The synthesis is a fast, simple and inexpensive process and such nanosized YFeO3 has a potential application in photocatalysis under visible light irradiation due to its structure of perovskite-type and photo-absorption property.
Introduction Technologically, the perovskite-like rare-earth orthoferrites (RFeO3) have formed an important class of the mixed-oxide systems and remain prominent in heterogeneous catalysis and surface chemistry because of their interesting physicochemical properties [1].
Also, calcination temperature has affected the phase structure, which can be seen from fig 2(a, b, c).
The processing chemistry is highly depended on the microwave irradiation condition and calcination temperature.
The obtained phase pure YFeO3 nanocrystalline is illustrated to be potential visible-light driven photocatalyst, attributing to its structure of perovskite-type.

The TEM image of synthesized AuNPs also showed that most nanoparticles were in a spherical shape and XRD pattern presented an intense peak at 2θ = 38.44°, 44.41°, 65.03° and 77.58°, respectively which correspond to face centered cubic structure with (111), (200), (220) and (311) plane.
The structure and composition were analysed using powder X-ray diffraction (XRD).
The results showed an intense peak at 2q = 38.44°, 44.41°, 65.03° and 77.58°, respectively which correspond to face centered cubic structure with (111), (200), (220) and (311) plane.
The authors would like to thank Agri Inno., Program of Applied Chemistry, Chemistry, Faculty of Science, Maejo University for the facilities provided to conduct the study.

Phase-Structure Transformation in Low-Si/Al-Ratio Geopolymers Wang Yi-pina, He Yanb, Liu Jingc, Cui Xue-mind Guangxi Key Lab of Petrochemical Resource Processing and Process Intensification Technology; School of Chemistry and Chemical Engineering, Guangxi University, Nanning, 530004, P.R.
In fact, previous studies [2,5] indicate that the structure of geopolymers is zeolite-like.
The alkalinity of geopolymers is an important factor that determines phase structure [7].
The results also show that the phase structure of geopolymers may transform into a crystalline structure under the appropriate compositions and external conditions.
