Rietveld refinement of X-ray diffraction pattern shows that all the samples are in single phase having wurtzite structure. It also confirms that Cr-ions are well incorporated into host lattice without changing the wurtzite structure of ZnO host lattice. X-ray diffraction and transmission electron microscopy observations showed the nanocrystalline nature of the samples. UV-Vis measurements show that the band gap is blue shifted in lower Cr-concentration and red shifted in higher Cr-concentration. This may be attributed due to the Burstein-Moss effect that prevails throughout this range of doping and sp-d exchange interaction which plays a significant role for higher Cr-concentration.","PeriodicalId":16850,"journal":{"name":"Journal of Physics C: Solid State Physics","volume":"80 1","pages":"254-255"},"PeriodicalIF":0.0,"publicationDate":"2013-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89919521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our studies show that it undergoes a reversible phase transition to the rhombohedral corrundum phase at ∼ 30 GPa. However, the diffraction peaks of the released phase are very broad and are overriding on a large background. This indicates that there is some disorder in the indium oxide lattice on release of pressure. The bulk modulus of the initial cubic phase was determined to be 186 GPa. It was observed that beyond 20 GPa the lattice of iron doped indium oxide became very incompressible with an average compressibility of 0.16 % compared to ∼ 0.5 % for the initial phase. This may be attributed to iron doping.","PeriodicalId":16850,"journal":{"name":"Journal of Physics C: Solid State Physics","volume":"47 1","pages":"104-105"},"PeriodicalIF":0.0,"publicationDate":"2013-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81199164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
