Materials with photo catalytic properties are widely studied because of their numerous applications. These applications include solar cell application and other photodegradation properties too. This photodegradation property include the waste water management too. This paper reports the synthesis and characterization of europium tungstate nanocomposites and explain their photocatalytic applications. The synthesis is carried out with hydrothermal method. XRD, FTIR, SEM and PL studies have been used to study the structural and morphological and optical studies. From these characterizations the sample is studied and further studied for its future uses. Keywords:. 1.1 INTRODUCTION. The cornerstones of nanoscience and nanotechnology are known as nanomaterials. In a few years back, the nanomaterials are grown for the development activities in an interdisciplinary area of research. It has a broad area for conducting the research. In structural and nonstructural applications, the nanomaterial has some useful properties which can be exploited. It is already having a significant commercial impact, which will assuredly increase in the future. In all around the world, the nanotechnology can be used to develop the technical aspects and for the improvement in life and social benefits. In nanomaterials there are different forms such as nanorods, nanotubes, nanocomposites, clusters etc. The material which can be converting nanosized particle into a matrix form of standard materials is known as nanocomposites. This type of materials can be prepared by any combination of materials and the material such as metal, ceramics, and polymers. By the addition of particles, the result showed that the drastic improvement in properties can be changed, the changing properties of the materials such as mechanical strength, toughness, electrical and thermal conductivity. The nanoparticle is very effective when the amount of materials is added normally in a range between 0.5% & 5% by weight. Like nanomaterials, nowadays nanocomposites also used in common in this technological society[1-2]. Applications of nanocomposites include electro catalyst in batteries, in fuel consumption this material is used as a lightweight materials, used as a artificial joints, carbon nanotubes can be made with nanocomposites fibers , marine application, food packaging, fuel tanks, films, environmental protection, flame ability reaction , erosion and corrosion application, capacitors for computer chips, Automotive engine parts, Oxygen and gas barriers, non-linear optics, battery cathodes, and ionic, nanowires, sensors, etc. 1.2 MATERIAL AND METHOD The materials were used for the synthesis of Eu2 WO6 were Sodium tungstate (Na2 Wo2). (0.05M)(1.65 g),Sodium hydroxide (NaOH) (4g),Europium nitrate [Eu(NO3)] (0.243g)purchased from Sigma-Aldrich and Deionized water(100 mL). The preparation was done by using hydrothermal method. For the preparation of a sample Eu2WO6.First, take a 1.65g of sodium tungstate and dissolved it with 100 ml of deionized water and stirred it for 30 min. After stirring it to add 0.243g of Europium nitrate Eu (NO3) into a sodium tungstate solution at room temperature and stirred the solution. When the stirring is going on, the NaOH solution is poured into the solution drop by drop till the solution were adjusted into a pH level 10 to get the complete precipitation of Eu2WO6. Then the resulted solution was filtered by using filter paper. After the filtration, the sample was collected and kept it in the hot air oven for 14 hr at 110˚C[11]. When the sample is taken from the hot air oven, the sample is filled with distilled water and keeps the sample in a cold place till the white precipitate is present under the container. After the white precipitate is appear the sample is taken into an oven at 120˚c and the sample is kept in a muffle furnace at 110˚c. After this procedure was done, the sample was seen in the form of powder, so the powder sample is collected from the furnace and further carried out for different characterization.[12].
