Fig. 4: Luminescent performances.

Comparison on a PL spectra, b Internal/external quantum efficiency(I/EQE) and absorption efficiency (Abs) of the SCASN:Eu phosphor-in-glass film (PiGF) fabricated by traditional sintering (TS) and rapid thermal annealing (RTA); the data of original phosphor powders are also presented for references. c IQE of SCASN:Eu phosphor-in-glass film prepared by RTA (S-PiGF-RTA) as compared with those reported red all-inorganic material (see details in Supplementary Table 4). d Digital photograph of the phosphor wheels. e Luminous flux and f luminous efficacy of the phosphor wheels as a function of the incident laser power and power density. g IQEs of the fabricated nitride and oxynitride PiGFs via the RTA and TS methods and the original phosphor powders. h Corresponding Luminous flux values of nitride and oxynitride phosphor wheels prepared by RTA technique as a function of incident laser power and power density. i Comparison of EL spectra of SCASN:Eu PiGF phosphor wheels laminated with and without silver-plated aluminum plates under 27 W mm⁻² blue laser excitation. In e, f, and h, the upper x-axis represents the incident laser power, while the lower x-axis represents the incident laser power density; The incident laser power density is calculated by dividing the incident laser power by the spot area (spot area: 0.628 mm²).
