Development of complex magnesium fluoro aluminates via the fluorolytic sol-gel synthesis
The diverse industry for optical applications demands materials with many exceptional properties, which often can only be ensured by the development of novel compounds. Specifically, the stability towards abrasion or moisture should go hand in hand with optical characteristics like a low refractive...

| description | The diverse industry for optical applications demands materials with many exceptional properties, which often can only be ensured by the development of novel compounds. Specifically, the stability towards abrasion or moisture should go hand in hand with optical characteristics like a low refractive index or high transmittance. Hence, we present fluorolytic sol-gel syntheses of complex magnesium fluoro aluminates and examine resulting layer applicability. Using
