Herein, the strategy of replacing Ge4+ with smaller Si4+ was adopted to realize the site-selective occupation of Bi3+ activator in the small ring and obtain a near-infrared light-emitting in Zn-2(Ge,Si)O-4. The designed phosphor exhibits a broad NIR emission with FWHM approximate to 104 nm in the 650-860 nm region, with a center emission wavelength of about 750 nm. Interestingly, the more sensitive four-member ring sites gradually replaced the six-member ring sites and realized a large-scope photoluminescence regulation from blue to NIR by just after the crystal field engineering. The possible...
