XRD pattern of SrZnP 2O 7 (1) is in well agreement with the standard PDF File no. X-ray diffraction pattern of CaZnP 2O 7 material. In present investigation the efforts have been taken to substitute zinc (Zn) as a secondary host along with strontium (Sr), barium (Ba), and calcium (Ca) as a primary host to obtain XZnP 2O 7 (X = Sr, Ba, Ca) pyrophosphate phosphor.įig. with a replacement of boron in Sr 2P 2O 7 with a composition 2SrO, 0.84P 2O 5, and 0.16B 2O 3 and it has been perceived that this material perseveres the tetragonal crystal coordination with lattice constants a = 6.92 Å and c = 9.51 Å the accurate chemical formula was computed by Smets to be Sr 6B(PO 4) 5 on the basis of lattice vectors in connection with Sr 2P 2O 7 pyrophosphate. Sr 6BP 5O 20 phosphor was primary cohost material testified by Murakami et al. Physical approaches of analysis play a vital role as long as an understanding of this pyrophosphate structure is concerned. There is a on-going request for novel phosphors in the fluorescent lamp engineering and search for appropriate host constituents are basically because of their chemical nature. Abdul Hakeem Deshmukh, in Optical Properties of Phosphate and Pyrophosphate Compounds, 2021 6.3.1 X-ray diffraction study
prepared a new crystalline form of pravastatin sodium and studied the X-ray powder diffraction data, the differential scanning calorimetry and thermogravimetric analysis, and other experiments for the drug form. 12.4, which shows the amorphous nature of the developed activated carbon. Among the crystalline structure, Scherrer's formula can be utilized to estimate the particle size using the peak data. If a sharp peak is observed, it infers a crystalline nature otherwise, an amorphous nature of the surface is inferred. The analysis of the XRD is on the basis of the peak observed. The angle 2 θ in the setup of the XRD fluctuate in a range of 10–90 degrees at a measurable step of 0.01 degrees. For the analysis, diffractometers utilize different radiations such as Cu-Kα radiation with a wavelength of 1.54 Å. One of the most used XRD analyzer is Rigaku Miniflex II. For the XRD analysis, very small amount of material is utilized of an order of 0.2 g, which is finely powdered and consistently dispersed on the testing plate. This analysis will enlighten about the crystallanity or the amorphous nature of the testing materials. X-ray powder diffraction (XRD) is also utilized to study the surface property.
