• The spinel limn2o4 is synthesized by the citrous acid method . the x - ray diffraction pattern of limn2o4 show that the product is a spinel phase with a = 0 . 824nm cubic unit cell
• The x - ray diffraction patterns and raman spectra indicated that zns fully transformed into zno with a polycrystalline hexagonal wurtzite structure when zns thin films were oxidized at annealing temperature of above 700 oc in an oxygen ambient
• As shown by uv - vis spectra , the contents of these europium - containing polyoxometalates in the composite films increase with the exchange time and become saturated after a number of days . x - ray diffraction patterns indicate the regular multibilayer structures of these composite films
• By analyzing the microstructure of as - cast alloys with different surplus of samarium added , the optimum surplus of samarium is decided . by comparing the microstructure of the alloys annealed for different time , the ideal and economical annealing time is confirmed . the microstructure and phase composition of alloys during the whole preparation of sm2fe17nx are analyzed using the scanning electron micrograph with energy - dispersive x - ray analysis and x - ray diffraction patterns
• The enhanced photoconductive effect from small amount of tnf facilitates the preparations of new organic photoconductive devices under the drive of low fields . in the fourth chapter , inclpc nanoparticles embedded in poly ( n - vinylcarbzaole ) ( pvk ) were prepared successfully by dissolving inclpc in aprotic organic solvent / lewis acid with great concentration for the formation of electron donor - acceptor complexes , i . e . , the method of complexation - mediated solubilization . the fabricated inclpc nanoparticles were characterized by means of uv / vis absorption , x - ray diffraction pattern , and tem
• This work emphasized the syntheses of perovskite templates ( including srtio3 and baho3 ) . batio3 were prepared by molten salt synthesis ( mss ) . scanning electron microscopy ( sem ) and x - ray diffraction patterns ( xrd ) revealed that there was no aggregation with batio3 powders and spherical particles of batio3 was obtained by mss
