Description

technical field

[0001] The invention belongs to the field of semiconductor optoelectronic materials, and in particular relates to a multi-element-doped strontium phosphate luminescent thin film and its preparation method and application. Background technique

[0002] Thin film electroluminescent display (TFELD) has attracted widespread attention and developed rapidly due to its advantages such as active light emission, full solid state, impact resistance, fast response, large viewing angle, wide application temperature, and simple process. The monochromatic TFELD with ZnS:Mn as the light-emitting layer has been developed and commercialized. At present, the research focus of TFELD is the improvement of the brightness of blue light, so as to realize color and even full-color TFELD.

[0003] In luminescent system materials, Sr 2 P 2 o 7 :Eu, Sr 2 P 2 o 7 :Sn and (Sr, Mg) 2 P 2 o 7 : Phosphoric acid phosphors such as Eu can get good excitation from blue to ultraviolet....
