Sputtering method of producing and electroluminescent device with improved blue color purity |
| abstract |
Disclosed is a method of producing an electroluminescent (EL) device having a CaGa2S4:Ce luminescent layer. The ratio of the X-ray diffraction peak intensity I2 for the (200) reflection of CaS to the X-ray diffraction peak intensity I1 for the (400) reflection of CaGa2S4 as appearing in the X-ray diffraction spectrum for the luminescent layer, I2/I1, is 0.1 or less. The amount of the impurity CaS in the luminescent layer is reduced. The EL device produces blue emission with high purity. |
