| Abstract | In white-light laser diodes (LD) illumination, the full width at half maximum (FWHM) of the emission spectrum of blue LD is too narrow, leading to the cyan light deficiency, while the emitting color of the material limits the red component of the device. Therefore, in this paper, Ca3-xLuxSc2-xMgxSi3O12:Ce3+ (CLSMS:Ce3+, x = 0, 0.5, 1, 1.5, 2) phosphor samples were successfully prepared based on Ca3Sc2Si3O12 (CSS) cyan-green fluorescent materials with different concentrations of Lu-Mg ions introduced in the matrix instead of Ca-Sc ions. And their luminescence properties were systematically investigated. The peak of the sample was shifted from 508 nm to 590 nm as the concentration of Lu-Mg increased. The thermal stability of the series phosphors gradually deteriorated with increasing Lu-Mg concentration. At 423 K, the emission intensity of the samples was 98.11 %, 94.13 %, 92.18 %, 81.96 % and 77.60 % of that at 298 K, respectively. And the thermal quenching activation energy also gradually decreases. The CLSMS:Ce3+ fluorescent materials were prepared into LD devices and tested. It was found that the series of samples showed a gradual decrease in cyan-green light and a gradual increase in red light with increasing Lu-Mg concentration. The CSS compounded with CaLu2Mg2Si3O12 (CLMS) obtained a white LD device with color coordinates of (0.3440, 0.3455), and the cyan and red components of the samples were compensated. In summary, this study demonstrates that CLSMS:Ce3+ is a very promising fluorescent material to extend the color gamut coverage of fluorescent materials. And it has a potential reference value for the field of white-light LD lighting. |
