Currently Cr3+ ion-activated broadband near-infrared (NIR) phosphors for phosphor-converted light-emitting diodes (pc-LEDs) are receiving much attention. However, developing a high quantum yield (QY) and excellent luminescence thermal stability of with an emission peak exceeding 850 nm is still great challenge. In the present work, ZrTe3O8:Cr3+ (ZTO:Cr3+) phosphor has been prepared via high-temperature solid-state reaction method, its NIR wavelength ranges from 700 to 1200 889 full width at half-maximum (fwhm) up 195 under 455 light excitation. Partial substitution Zr4+ ions by Ti4+ in enhances intensity 1.65-fold. The optimized ZTO:Cr3+, exhibits internal efficiency (IQY) 64.9% remains 73.82% room temperature (298 K) when increased 423 K. This indicates that long-wavelength developed work both IQY, which promising night vision, nondestructive testing, bioimaging applications.
