Combustion Synthesis of Gd_2O_2S:Tb~(3+)X-ray Nanometer Phosphors
Study on the process for the combustion of CaAl_2O_4:Eu~(2+),Nd~(3+) fluorescent powder
The grain of fluorescent powder monishes and the intensity of the transition ~5D_0→~7F_2 decreases with the calcining temperature. But the intensities of the transitions ~5D_0→~7F_1 and ~5D_0→~7F_4 change little.
The width of the emission spectrum is obviously widened. The grain of fluorescent powder minishes and the intensity of the transition 5Do→7F2 falls along with the calcining heat falls. But the intensities of the transitions 5D0→7F1 and 5D0→7F4 change very little.
The luminescent spectra of them showed a notable blue shift in excitation spectra and a red shift in emission spectra compared with those of the normal Y2O3∶Eu3+ nano-particles fluorescent powder.
In this paper the system structure of fluorescent powder surface process system and thedesign of hardware and software are in detail presented by use of OMRON CQM1H PLC.
