YANAN ZHU1, MINGQIAO GE1,*
Luminescence composite was fabricated by combining red organic fluorescent pigment on to SrAl2O4:Eu2+, Dy3+ particles. X-ray diffraction (XRD) patterns, PR-305 afterglow brightness tester and Fluorescence spectrophotometer (HITACHI 650-60, Japan) as well as PR–650 Spectra Scan colorimetric were used to characterize the properties of the luminescent composite. The emission behavior was evaluated by Fluorescence Spectrophotometric analysis and the results demonstrated that the emission spectra of samples had a red shift under visible light (λ=520 nm) excitation. The emission intensity of the red organic fluorescent pigment-doped hybrid increased with the increase of red organic fluorescent pigment concentration, but the afterglow brightness reduced. Furthermore, the emission colors of SrAl2O4:Eu2+,Dy3+/ red organic fluorescent pigment also can be tuned from yellow to orange-red easily by changing the doping concentrations(N) of red organic fluorescent pigment..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
