The photoluminescence strength of Mg3Y2(1- y )Ge3O12yEu3+, Mn4+ (0 ≤ y ≤ 1) phosphors constantly enhances with rising temperature from 298 to 523 K predicated on Eu3+ → Mn4+ energy transfer. For Mg3Eu2Ge3O12Mn4+ test, the incorporated intensity at 523 K remarkably achieves 120% of the at 298 K. Interestingly, through codoping Eu3+ and Mn4+ in Mg3Y2Ge3O12, the photoluminescence shade is controllably tuned from orangish-red (610 nm) to deep-red (660 nm) light by switching Eu3+ concentration
