dc.description.abstract | Until now, because of the being a candidate for the red-emitting material the CaAl12O19:Mn4+ phosphor (CAO:Mn) has been widely used especially in white light-emitting diodes (WLEDs). In this study, the emission-based luminescence properties of CaAl12O19:Mn4+ red phosphor synthesized via sol-gel method was studied in the absence and presence of Er3+- and Tb3+-doped 13–93 bioactive glass powders in ethyl cellulose (EC) matrix in detail. Upon the addition of un-doped and Er3+- and Tb3+- doped bioactive glass powders, the CAO:Mn phosphor resulted in 44%, 92% and 88% increase in the emission intensity, respectively. The luminescence and decay time characteristics of the synthesized phosphor were also investigated in terms of microsecond time scale. The proposed material may bring a new inside for the existing problems of the red phosphors regarding the brightness, colour correlation temperature and colour rendering index. © 2021 Elsevier B.V. | |
