“…To uncover the origin of low thermal conductivity, we can refer to the Eq. (8). According to the equation, low density, large average mass per atom and low Young's modulus would result in low j min .…”

“…Due to the unusual crystal structure, the metal cations in the TiP 2 O 7 and HfP 2 O 7 lattice are well separated. This geometric configuration is beneficial to avoid nonradiative deactivation of the activators, and ensures TiP 2 O 7 and HfP 2 O 7 to be good luminescent host materials for rare‐earth activators, for example, (Hf 0.89 Eu 0.11 )P 2 O 7 phosphor shows intense blue emission, which is assigned to the transition from 4f 6 5d 1 to 4f 7 of Eu 2+ . MP 2 O 7 are also considered as promising catalyst and catalyst support for other catalytically active inorganic species .…”

“…Phosphate-based phosphors have attracted much attention in recent years as they have excellent thermal stability and good charge stability due to rigid tetrahedral threedimensional matrix of phosphate [6][7][8][9]. In particular, Eu 2+ -doped pyrophosphates belonging to the A 2 P 2 O 7 and ABP 2 O 7 families (where A and B are divalent cations) are one class of desirable blue phosphors as they possess a few interesting characteristics such as high luminescence efficiency upon blue or near-UV LED excitation, good thermal and chemical stability [9][10][11][12][13][14][15][16][17]. Browsing the literature, we found that the co-doping blue emitting ions as co-activators into any matrix was extensively studied by numerous scientists.…”
