Microstructure and Optical Properties of SPION/Sr3V2O8:Er3+, Yb3+ Nanocomposites Synthesized by Microwave-Assisted Metathetic Method

“…5b it can be depicted that the peak positions are practically the same, while the intensities obtained from Sr3V2O8:Er 3+ , Yb 3+ (SVO:ErYb) are slightly higher than those of SPION/Sr3V2O8:Er 3+ , Yb 3+ (F-SVO:ErYb). The internal vibration mode frequencies are dependent on the lattice parameters and the degree of the partially covalent bonding between the cations and molecular ionic group [VO4] [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] . The Raman spectra of the synthesized Sr3V2O8:Er 3+ , Yb 3+ (SVO:ErYb) and SPION/Sr3V2O8:Er 3+ , Yb 3+ (F-SVO:ErYb) nanocomposites indicate additional peaks at both higher (806 and 725 cm -1 ) and lower frequencies (288 and 242 cm -1 ), which are attributed to the doping ions of Er 3+ and Yb 3+19-21 .…”

“…The metal orthovanadates have been developed to enhance the applications of metal orthovanadate prepared by a range of processes, such as a solid-state reaction 4,5 , the solution phase metathetic method 6 , the sol-gel 7 , the solid-state metathesis approach 8 , the mechano-chemical method 9 and the floating zone technique 10 . Among different methods, solution-based chemical synthetic methods play the key role in the design and production of fine oxide powders and are successful in overcoming many limitations of traditional solid-state, hightemperature methods.…”

Polymorphism and Optical–Vibration Properties of MnV2O6·nH2O (n = 0, 2, 4) Prepared by Microwave Irradiation

“…The chemical and physical properties of these materials are closely related to their structures and morphologies, which are an outcome of the synthetic pathway . Previous reports show that manganese vanadates phases can be obtained by solid-state reaction, ,,, conventional hydrothermal synthesis, ,,,, coprecipitation, ,, polymer gelatin method, and microwave radiation. , It is generally accepted that the hydrothermal method presents some advantages over these processes listed above in obtaining pure crystalline phases without additional heat treatment, spending less time and energy. Moreover, in the last few decades, it was observed that the application of microwave irradiation into hydrothermal reactors is a viable alternative to reduce temperature and time conditions .…”

Microwave-Assisted Solvothermal Synthesis and Characterization of M3V2O8 (M = Ca, Cd) Nanoparticles

“…Several processes have been developed over the past decade to enhance the applications of metal orthovanadates prepared by a range of processes, such as a solid-state reaction 4,5 , a solution phase metathetic method 6 , sol-gel 7 , a solid-state metathesis approach 8 , mechano-chemical method 9 and floating zone technique 10 . The chemical reactions between precursors powders have emerged as an attractive method to synthesize novel materials.…”
