Abstract

A very high efficiency method using microwave heating to synthesize Sm3+ doped ultra-fine (sub-micro) powder is shown in this paper. We studied the absorption spectrum of the powder, and we find that there are many absorption peaks. Based on the absorption property of this powder, we make a laser protection coating at 9398 cm-1. The coating reduced the reflected light power by 89% compare to the one without coating. This shows that the as-prepared ultra-fine powder has great potentials in many aspects such as laser protective coatings, anti-counterfeiting inks and so on..
