Özet:

 

A new orthorhombic phase of Na2LaOPO4 (sodium lanthanum  oxyphosphate), and novel Na2NdOPO4 (sodium neodymium oxyphosphate),  Na2SmOPO4 (sodium samarium oxyphosphate) were synthesized by solid  state reactions of Na2CO3, NH4H2PO4, and Ln2O3  (Ln = La, Nd, and Sm).  The unit cell dimensions were calculated using  their X-ray powder diffraction data, which were a = 13.60(1), b =  12.71(1), and c = 6.96(1) Å, a = 13.466(5), b = 12.547(6), and c =  6.932(5) Å, and a = 13.54(1), b = 12.577(8), and c = 7.047(5) Å,  respectively, and the probable space group was Pmm2.  Using the same  procedure orthorhombic Na2DyOPO4 (sodium dysprosium oxyphosphate),  Na2HoOPO4 (sodium holmium oxyphosphate), Na2ErOPO4 (sodium erbium  oxyphosphate), and Na2YbOPO4 (sodium ytterbium oxyphosphate) were  also prepared for the first time in this work.  The IR data of the  compounds agreed with the values given in the literature.  The Raman  data and SEM micrographs of the synthesized compounds are given for  the first time in this report.
