Phase Equilibria in the System Nd2O3-P2O5-H2O at 500°C under 100 MPa and Synthesis of NdP5O14 Crystals

Synthesis and Nd3+ Luminescence Properties of ALa1–xNdxP4O12 (A = Li, Na, K, Rb) Tetraphosphate Nanocrystals

“…Therefore the neodymium tetra-and penthaphosphates are especially attractive for laser application, which was confirmed by great number of publications concerning laser action of LiNdP 4 O 12 12-15 and NdP 5 O 14 [1][2][3][4][5][6][7][8][9][10][11] .…”

“…A high number of optically active ions is a suitable feature for size minimization of lasers. Therefore, the neodymium tetra- and penthaphosphates are especially attractive for laser application, which was confirmed by a great number of publications concerning laser action of LiNdP 4 O 12 − and NdP 5 O 14 . − …”

“…The neodymium-based stoichiometric phosphor crystals were extensively investigated in 1970s and 1980s of the last century as an interesting alternative for well-known laser crystal-like YAG:Nd, etc. − This interest was justified by the unique optical properties of these materials: the reduced cross relaxation, low laser action threshold, high absorption cross section. The most investigated stoichiometric phosphors were tetra- and pentaphosphates associated with the large Nd 3+ –Nd 3+ distance (around 5.5–6 Å).…”
