Here, near-infrared broad dual-band emission phosphors were achieved through energy transfer between Cr3+ and Ni2+ ions in the β-Ga2O3 host. All samples co-doped with exhibit covering 600–1700 nm under 430 excitation. Thanks to doping of ions, intensity Ga2O3:Cr3+, has increased by about 2.4 times internal quantum efficiency 83.2% compared Ga2O3:Ni2+ phosphors. Meanwhile, when fluorescence lifetime was monitored at 745 nm, an efficient host verified. Due significant differences temperature-sensitive properties a thermometer designed utilizing ratio technology, achieving maximum relative sensitivity 5.26% K–1, which surpasses most optical temperature measurement This suggests that hold promise as potential candidates for materials. Additionally, broadband sample been investigated applications component analysis night vision, demonstrating its versatility multifunctional applications.
