GdCa_4O(BO_3)_3晶体的Bridgman法生长条件探索

Inorganic nonlinear optical crystal GdGa 4O(BO 3) 3(GdCOB) possesses moderate NLO efficient (1.3pm/V) ,high damage threshold(1GW/cm 2),and wide transmission wave band(320-2700nm).In addition,it is chemically stable,nonhygroscopic and easy to process,which makes GdCOB a promising practical NLO material for frequency conversion.Crack free single crystals of GdCOB with large size have been grown using the vertica...  (本文共1页) 阅读全文>>

GdP_5O_(14):Sm~(3+),Pr~(3+)晶体的研究

In this paper,the single crystals of GdP 5O 14 :Sm 3+ ,Pr 3+ (GdPP: Sm,Pr)were grown by the hydrothermal method.The process of growing crystal is th e formation and grown up of new phase. Whether new phase can appear and how can occur,which is driven by the force of phase transformation.It is necessary to co ntrol this process by the concentration in the hydrothermal solution.In the syst em of cohesive...  (本文共1页) 阅读全文>>
