Abstract: L-arginium diphosphate (LADP) is one of the important analogs of LAP crystal. LADP has excellent optical, thermal and mechanical properties, which make it a potential candidate for photonics device fabrication. The present work deals with the growth and characterization of metal (Cu2+ and Mg2+) substituted single crystals of LADP. The grown crystals are subjected to single crystal XRD, AAS, FTIR, DRS spectra and microhardness studies. Microhardness studies indicate that the presence of dopant has enhanced the hardness of the material. The photoconductivity study reveals the positive photoconducting nature of both pure and doped crystals.
