A series of novel yellowish green emitting phosphors Sr3P4O13:Tb3+ have been synthesized successfully via a conventional high temperature solid state reaction, and characterized by X ray diffraction, photoluminescence excitation/emission spectra and decay curve for the first time. The concentration quenching phenomenon of Tb3+ was observed, and the optim al doping concentration of Tb3+ in Sr3P4O13 was ab out 0.1. T he critical distance of Tb3+ ion was calculated to be about 17.3 Å, indicating the multipole multipole interaction could play an important role on the concentration quenching phenomenon of Tb3+ in Sr3P4O13 host. The average decay time and CIE chromaticity coordinates w ere also determined for Sr3P4O130.1Tb3+ phosphor with optimal photoluminescence intensity. The as prepared Sr3P4O13:Tb3+ phosphor could be excited by ultraviolet, and exhibit yellowish green emission with short decay time of milliseconds, indicating the potential application in display and lighting region..

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.
