  • 简介:Sodiumparanitrophenolatedihydrate(NPNa·2H2O)isanexcellentsemiorganicnonlinearoptical(NLO)material,crystallizesbothinwaterandmethanolwithhighdegreeoftransparency.Goodopticalqualitysinglecrystalsofdimensionupto18mmx6mmx3mmareobtainedbyisothermalsolventevaporationtechnique.Thesolubilityofthecrystalindifferentsolventswasmeasuredgravimetrically.ThesinglecrystalsofNPNa·2H2Oshowvariationinphysicalpropertiesandgrowthrateindifferentsolvents.Methanolorethanolsolutionyieldscrystalsofbipyramidalshapewithclearmorphology.However,methanolgrowncrystalisexhibitingimprovedhardnessparametersandpossessesexcellentthermalstabilityascomparedtowatergrowncrystals.TheeffectsofsolventonhardnessparameteralongwiththermalandopticalpropertiesofNPNa·2H2Owasrevealedinthispaper.
