Abstract

Recent advances in the synthesis of inorganic materials have enabled a wide range of control of particle size, composition, phase, and morphology that can be tuned in the design of future levitated optomechanical sensors. This talk will describe recent results in the hydrothermal synthesis and characterization of two-dimensional microprisms of hexagonal sodium yttrium fluoride crystals based on novel molecular ligands. Hexagonal cavities with high aspect with high aspect ratios of ~50 are observed with potential applications in the detection of high frequency gravitational waves, radiation balanced microlasers, and the solid-state laser cooling of quantum sensors.
