Study of the structure of 3D-ordered macroporous GaN–ZnS:Mn nanocomposite films

A film-type 3D-ordered macroporous GaN–ZnS:Mn nanocomposite with the structure of an inverted opal is fabricated. Structural studies of the nanocomposite are performed, and it is shown that GaN and ZnS:Mn introduced into the pores of the silica opal are nanocrystallites misoriented with respect to each other. It is shown that the nanocomposite is a structurally perfect 3D photonic crystal. The efficiency of using a buffer of GaN crystallites to preclude interaction between the surface of the spherical $a$-SiO$_2$ particles forming the opal matrix and chemically active substances introduced into the pores is demonstrated.
