Although significant achievements have been made in blue and green persistent luminescent (PersL) materials, the research and development of PersL materials in the warm-color region (550\u2013660 nm) are relatively lacking. Only the orange PersL phosphor Y2O2S:Eu3+,Mg2+,Ti4+ (\u223c610 nm) and deep red PersL phosphor (Ca1\u2212xSrx)S:Eu2+,Tm3+ (\u223c650 nm) fulfill the demands of commercial applications. However, sulfide phosphors have poor chemical stability and a relatively short persistent duration time. Herein, we report a series of orange PersL materials, (Sr1\u2212xBax)3SiO5:Eu2+,Nb5+, which exhibit a strong PersL emission band at 550\u2013670 nm and a super-long persistent time of more than 20 h at the 0.32 mcd m\u22122 threshold value after UV radiation. These new orange PersL materials are compared to the commercial warm-color sulfide PersL phosphor, Y2O2S:Eu,Mg,Ti, with regards to PersL time and brightness, and it is determined that they would have great potential applications <a href=\"https:\/\/www.eastgonflable.fr\/e106058-air-track-gym.html\" style=\"color: grey; text-decoration: none;\">airtrack<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mater.
