text: Yo, check it out, I got something to say,
  About a five-layer antireflective coating, okay?
  It's for the visible and infrared, a real cool trick,
  Made on a quartz substrate, that's slick.
  
  Using a solgel route, they successfully fabricated,
  A coating that keeps the reflections faded.
  Optimized with an optical admittance approach,
  A quarter-half-quarter structure, I gotta coach.
  
  The top layer's a mesoporous SiO2 film, no doubt,
  Made with a triblock copolymer, it's what it's about.
  The other layers are SiO2-TiO2 hybrids, you see,
  All aligned and ordered, as can be.
  
  Grazing incidence small-angle x-ray scattering,
  Showed the mesopores, no need for battling.
  And the hybrid films, they're homogenous and tight,
  Just what you need for this coating's light.
  
  They analyzed the transmittance spectra with care,
  To get the thickness and refractive index, they were aware.
  These parameters, they're crucial, don't you know?
  For the theory designs, they're ready to show.
  
  To prevent cracks, they had a clever plan,
  A short heat treatment and a shock cooling span.
  The film stacks stayed intact, no need to worry,
  They kept it smooth, no need to hurry.
  
  The result? An antireflective coating so fine,
  Transmittance exceeding 99%, that's the bottom line.
  From 500 to 700 nm, it's pure perfection,
  And in the infrared, it's 97.84% in the right direction.
  
  So this work, it's a beneficial attempt, you see,
  To create antireflective coatings with solgel, fancy and free.
  With a multilayer structure, they brought the heat,
  Keeping those reflections away, a true feat.
