Yttrium(II) oxide or yttrium monoxide is a chemical compound with the formula YO.
This chemical compound was first created in its solid form by pulsed laser deposition, using yttrium(III) oxide as the target at 350 °C.
The film was deposited on calcium fluoride using a krypton monofluoride laser.
This resulted in a 200 nm flim of yttrium monoxide.
