Abstract Luminescence intensity decreasing with rising temperature is a common phenomenon called thermal quenching. However, the Bi 3+ ‐Eu co‐doped NaGd 2 Ga 3 Ge O 12 (NGGG) phosphor exhibits antithermal quenching luminescence of Eu . has pair thermally coupled energy levels (TCLs), where higher level P 1 and lower derived from metal‐to‐metal charge‐transfer (MMCT). As concentration increases, lifetime decreases, while MMCT remains unchanged. It means that transfer (ET) only happens between Interestingly, excited, emission still observed. This because when exciting level, as upper TCLs, can also be which consequently leads to Accordingly, ⁺ will increased show coupling process enhanced temperature. Taking advantage unique ET ⁺, ⁺‐Eu NGGG demonstrates sensitivity 2.08% K − ¹ at 500 K, distinct most fluorescence thermometers maximum low temperatures.
