The chemical etching method was employed to study the defects in the structural morphology of Nd：GdNbO4 crystal with phosphoric acid etchant. Mechanical proper- ties （such as hardness, yield strength, fracture toughness, and brittle index） of the as-grown crystal were system- atically estimated on the basis of the Vickers hardness test for the first time. The transmission spectrum of Nd： GdNbO4 was measured in the wavelength range of 320- 2400 nm at room temperature, and the absorption peaks were assigned. Results hold great significance for further research on Nd：GdNbO4.展开更多
