Microstructure-dependent luminescent properties of thin-film ZnGa2O4:Mn2+ phosphors

Synthesis and characterization of a near-infrared persistent luminescent Cr-doped zinc gallate–calcium phosphate composite

“…The correlation between the loss of Zn and the decreased PL was also observed in a Mn 2+ -doped ZnGa 2 O 4 film previously, although such loss was induced by high temperature. 71 Our result agrees with their work, with EXAFS showing the direct evidence of the decreased Ga–Zn and Zn–Zn coordination numbers in CZGO–ACP.…”

Spectrum designation and effect of Al substitution on the luminescence of Cr3+ doped ZnGa2O4 nano-sized phosphors

“…This evolution indicates that the nucleation and crystallization process promotes more ideal Cr 3 + sites. The loss of Zn has been observed in several reports at high-temperature calcining process due to its high saturated vapor pressure [30,31] which reduces the amount of interstitial Zn 2 + ions. Thus, the intensity of N 1 line experiences a remarkable decrease with increase in the calcining temperatures.…”
