The authors have demonstrated white light emission of rare earth (RE)-free Mn-doped SnO-ZnO-P(2)O(5) glass. The RE-free glass shows white light emission with a high value of quantum efficiency (QE) comparable to conventional crystalline phosphor. It is notable that the high QE value is attained for RE-free transparent glass, and the broad emission can be continuously tuned by both the amount of activator and the composition of the glass. Since this glass possesses low-melting property, we emphasize that the glass phosphor will lead to the development of a novel inorganic white-light-emitting device in combination with a solid state UV light-emitting source.
作者展示了不含稀土元素的 Mn 掺杂 SnO-ZnO-P(2)O(5)玻璃的白光发射。这种不含稀土元素的玻璃表现出高量子效率（QE）的白光发射，与传统的晶态荧光粉相当。值得注意的是，这种高 QE 值是在不含稀土元素的透明玻璃中实现的，通过激活剂的量和玻璃的组成可以连续调节宽发射。由于这种玻璃具有较低的熔点，我们强调这种玻璃荧光粉将与固态紫外发光源结合，开发出一种新型的无机白光发光器件。
