[29] S03: 将发光玻璃 13及金属层 14在真空下进行退火处理, 使金属层 14形成金属 显微结构, 冷却后形成发光元件 10。
[30] 在步骤 S01中, 发光玻璃 13制备步骤如下: 按照发光玻璃的化学成分中的摩尔 份数来称取各成分的金属氧化物, 在 1200〜1600°C温度下熔融, 冷却至室温, 再置于还原气氛中, 在 400°C
~750°C温度下退火 3~12小吋, 制得发光玻璃。 具体制备步骤如下: 以分析纯的 碱金属盐、 Si02、 ZnO、 Mn02为主要原料, 按照发光玻璃 aR2ObZnOcSi02*nMn
02的各组分之间的摩尔份数比例, 来称取相应的原料, 在 1200〜1600°C温度下 熔融 1~5小吋, 冷却至室温, 再置于还原气氛中, 400~750°C温度下退火 3~12小 吋, 制得发光玻璃。 另外, 还可将制得的玻璃进一步切割、 抛光加工成一定的 尺寸, 以符合应用需求。
[31] 与前面描述的结构相类似, 此处形成金属层 14可以是釆用化学稳定性良好的金 属材质源沉积形成, 例如不易氧化腐蚀的金属, 另外也可以是常用的金属, 优 选为金、 银、 铝、 铜、 钛、 铁、 镍、 钴、 铬、 铂、 钯、 镁、 锌中的至少一种金 属, 更优选为由金、 银、 铝中的至少一种金属。 在步骤 S02中, 该金属层 14是通 过将上述至少一种金属通过物理或化学气相沉积法形成于发光玻璃 13表面, 例 如但不限于用溅射或蒸镀方法形成于发光玻璃 13的表面。 金属层 14的厚度优选 为 0.5纳米〜 200纳米, 更优选为 1纳米〜 100纳米。
[32] 步骤 S03具体如下: 在发光玻璃 13表面形成金属层 14后, 在 50°C~650°C下进行 真空退火处理, 退火吋间为 5分钟〜 5小吋, 然后自然冷却至室温。 其中, 退火 温度优选为 100°C~500°C, 退火吋间优选为 15分钟〜 3小吋。
[33] 请参阅图 1和 3, 说明本发明实施例的发光元件发光方法的流程, 该发光方法包 括如下步骤:
[34] S11 : 按照前述发光元件制造方法获得发光元件 10;
[35] S12: 对金属层 14发射阴极射线 16, 在阴极射线 16的激发下, 金属层 14与发光 玻璃 13之间形成表面等离子体, 使发光玻璃 13发光。
[36] 发光元件 10具有前面描述各种结构及组份等特征。 在实际应用中, 实现步骤 S1 2可以釆用场发射显示器或照明光源, 在真空环境下, 阳极相对场发射阴极阵列 施加正向电压形成加速电场, 阴极发射阴极射线 16, 在阴极射线 16的激发下, 电子束首先穿透金属层 14进而激发发光玻璃 13发光, 在这个过程中, 金属层 14 与发光玻璃 13的界面上产生了表面等离子体效应, 通过该效应使发光玻璃 13的 内量子效率大大提高, 即发光材料的自发辐射增强, 进而大大增强了发光材料 的发光效率。
[37] 表面等离子体 (Surface
Plasmon, SP) 是一种沿金属和介质界面传播的波, 其振幅随离开界面的距离而 指数衰减。 当改变金属表面结构吋, 表面等离子体激元 (Surface plasmon polaritons, SPPs)
的性质、 色散关系、 激发模式、 耦合效应等都将产生重大的变化。 SPPs引发的 电磁场, 不仅仅能够限制光波在亚波长尺寸结构中传播, 而且能够产生和操控 从光频到微波波段的电磁辐射, 实现对光传播的主动操控。 因此, 本实施例利 用该 SPPs的激发性能, 增大发光玻璃的光学态密度和增强其自发辐射速率; 而 且, 可利用表面等离子体的耦合效应, 当发光玻璃发出光吋, 能与其发生耦合 共振效应, 从而大大提高发光玻璃的内量子效率, 提高发光玻璃的发光效率。
