Neodymium octanoate (NdOA) was synthesized from neodymium oxides and dissolved into poly(methyl methacrylate) (PMMA) forming a solid solution of Nd 3+ doped PMMA (Nd‐PMMA). Investigation of the absorption spectrum of Nd‐PMMA showed that it was similar to that of Nd 3+ doped silica glasses, but with about 5 nm of blue shift. The glass transition temperature ( T g s) of all the Nd‐PMMA samples were about 10°C higher than that of pure PMMA for Nd 3+ concentrations of 60–700ppm. The Nd‐PMMA was used to draw a fibre. The emission output of the fibre at 585 nm was observed under a green source pumping at 532 nm by optimization of the Nd 3+ concentration and the length of the fibre. Under 1 W pumping radiation, 60 μW output was obtained for the fibre with Nd 3+ concentration of 70 ppm and length of 15 cm.
