摘要
本文采用电化学阳极氧化法,在不同的电解液中通过改变电解电压、时间、电解液温度、浓度等因素制备出具有规则形貌和结构的钨酸盐,并对制备的钨酸盐进行光致发光性能研究。
     1.在饱和的Ca(OH)_2溶液中采用恒电压阳极氧化法制备出四方相CaWO_4晶态薄膜。该薄膜用波长250 nm光激发,在300 nm~600 nm波段有蓝绿色发射光产生。在45℃、20 V阳极氧化40 min所制备的CaWO_4薄膜均匀、致密,发射光相对强度最大。
     2.在Sr(OH)_2溶液中,采用恒电压阳极氧化法制备出四方相SrWO_4晶态薄膜,用波长200 nm光激发,在320 nm~420 nm波段有发射光产生。研究了电解电压、电解液温度、电解液浓度和时间对SrWO_4薄膜形貌和荧光性能的影响,在适中的电压、温度和低浓度电解液中制备的SrWO_4薄膜均匀致密,粒径较大,发射光相对强度较高,过高的电压、温度或浓度会造成薄膜缺陷增多,发射光相对强度减小。
     3.在Ba(OH)_2水溶液中,采用恒电压阳极氧化法制备出四方相BaWO_4晶态薄膜,用波长200 nm光激发,在300 nm~600 nm波段有发射光产生。电解电压、电解液温度、解液浓度和氧化时间对薄膜形貌,电解电压和氧化时间对荧光性能有很大影响。
In this paper, tungstate with regularly morphologies and structures weresynthesized using anodic oxidation by changing the voltage, time, temperature,concentration in the different electrolytes. Photoluminescence properties of preparedtungstate were also investigated.
     1. Crystallized CaWO_4 films with tetragonal phase were fabricated by anodizationin saturated Ca(OH)_2 solution. A set of anodization experiments were carried out inorder to investigate the influential factors on the morphology of calcium tungstatesurface. The experimental results show that a blue-green emission peak at 300nm-600 nm was obtained with excitation light of 250 nm. And the CaWO_4 filmprepared by anodization of tungsten at 45℃and 20 V for 40 min were uniform,dense, and had the best relative emission strength.
     2. Crystallized SrWO_4 films with tetragonal phase were fabricated by constantvoltage anodization in Sr(OH)_2 solution. The influences of reaction time, voltage,temperature and electrolyte concentration on morphology and photoluminescenceproperties of SrWO_4 films were analyzed. The experimental results show that ablue-green emission peak at 320 nm-420 nm was obtained with excitation light of 200nm. And the results show that SrWO_4 films with uniform, dense, large particles andhigh emission intensity were prepared in appropriate voltage, temperature, and lowelectrolyte concentration, while excess voltage, temperature or concentration madedefects increase and relative intensity of emission decrease.
     3. Crystallized BaWO_4 films with tetragonal phase were fabricated by constantvoltage anodization in Ba(OH)_2 solution. The influences of reaction time, voltage,temperature and electrolyte concentration on morphology and photoluminescenceproperties of BaWO_4 films were analyzed. The experimental results show that a blue-green emission peak at 300 nm-600 nm was obtained with excitation light of 200nm.
