Artificial lakes are important resources in China and the country enjoys the largest number of artificial lakes in the world.

SEM is an important means for the observation and study of the artificial opal photonic crystal.

The fabrication of artificial opals by sedimentation of SiO2 spheres in ethanol with an improved mold was presented.

SiP_2 artificial opal templates are fabricated,and metal organic chemical vapour deposition is used to infill the voids of prepared silica colloidal crystals with InP.
