The rantangarato luminescent material and its production method the rare earth ion which contains the metallic particle being doped

摘要

Topic Luminous efficiency is high, when it possesses the luminous efficiency which is superior, is excited the rantangarato luminescent material where the rare earth ion which contains the metallic particle where purity and brightness of discharge light are high, can apply to wide scope in various luminous instruments is doped and that its production method is offered are designated as purpose.SolutionsAs for the rantangarato luminescent material where the rare earth ion which contains the metallic particle which relates to this invention is doped, as for the general system, La_{1 xGaO3}: Ln it is _x and M _y, Ln is the rare earth ion, M is the metallic particle, x numerical range is 0.001 - 0.1, the numerical range of y is 0.00002 - 0.01. Because the metallic particle is added to the rantangarato luminescent material where the rare earth ion which contains the said metallic particle is doped, the luminous efficiency in the same excited condition improves largely, at the same time wave length of discharge light does not change.
