Transition metal light emission

The alkali metals in general yield intense visible light emission due to the radiative transitions of the S1 electrons. Further, the low ionization energy of these metals (Rb and Cs) results in ease of thermal electron emission which gives rise to a number of interesting applications. In fact, the use of Rb and Cs salts stems from these facts. [Pg.402]

Many transition metal ions are known as luminescent centers as for example Mn2+ in Zn2SiC>4 Mn with a broad emission band due to the electronic transition 4Ti (t eg) — 6A (t g e2). The emitted light is green. On the other hand, the emission band of Mn4+ in Mg4Ge05.5F Mn is narrow with some vibronic interaction structure. The emission in this compound is due to a spin flip transition in t g without any change in chemical bonding. [Pg.941]
