Description
Technical field
The utility model relates to liquid laser ablation technology field, exactly is the continuous preparation feedback of a kind of homogeneous phase colloid liquid phase laser ablation chamber.
Background technology
In the last few years, the liquid-phase pulse laser ablation technology had had bigger development, utilized its synthetic nano material to have that kind variation, pattern and structure are single, size distribution is more even.Characteristics such as utilize the nano material of this technology preparation, it is simple also to have building-up process, and method has versatility, can carry out the multi-parameter regulation and control, and the colloid of preparation is pure.Because its output is lower, be the bottleneck of its development of restriction always.Recently, Sajti group has reported and has utilized ps pulsed laser and ns pulsed laser, to α-Al
2O
3Ceramic material carries out liquid laser ablates, and its output can reach the per hour magnitude of a gram.Because the priority application of liquid laser ablation technology is also at laboratory stage, the device at ablation position be some mostly through the groove of simple designs or bottle and so on, what have is contained in target the bottom; Be rotated ablation; What have is built on stilts with target, is placed with magnetic agitation below, carries out magnetic agitation.
Experimental result shows that the fixing and rotation of target has great influence to synthetic colloid, and fixing target is easy to generate molten drop during ablation; The distribution of particles of colloid is uneven, and is simultaneously, also bigger to the destruction of target; Utilization rate is lower, these shortcomings that rotary target then can effectively be avoided, but when utilizing rotary target; Colloid does not stir; The colloidal solid concentration of ablation point position can be higher than the colloidal solid concentration of other position, if can not in time disperse the colloidal solid of higher concentration, can cause its local reunion.Please refer in detail: H. M.Zhang; C.H.Liang; Et al.Hydrothermal Treatment of the Colloids Induced viaLiquid-Phase Laser Ablation:A New Approach for Hierarchical TitanateNanostructures with Enhanced Photodegradation Performance.2011; CrystEngComm, DOI:10.1039/C1CE05136A.
