Terbium oxide (Tb4O7)nwere otutu ngwa, ma isi ihe eji eme ya bụ ihe dị ka akụkụ na mmepụta nke phosphor, nke bụ ihe ndị na-amụnye ọkụ mgbe ekpughere ya n'ụdị ike ụfọdụ, dị ka electrons ma ọ bụ ultraviolet (UV).Nke a bụ ụfọdụ isi ngwa nketerbium oxide:
1.Cathode Ray Tube (CRT) Na-egosiputa:Terbium oxidea na-eji phosphor nke ihe ngosi CRT, dị ka ihuenyo telivishọn nke ochie na ihe nlekota kọmputa.Mgbe electrons na-eti phosphor nke dabeere na terbium, ha na-ebunye ìhè a na-ahụ anya, na-emepụta ihe oyiyi na ihuenyo.
2.Fluorescent ọkụ:Terbium oxidena-arụkwa ọrụ na mmepụta nke fluorescent ọkụ, gụnyere fluorescent oriọna na kọmpat fluorescent oriọna (CFLs).Ọ na-enyere aka ịmepụta ìhè ọcha mgbe UV radieshon na-akpali mkpuchi phosphor n'ime oriọna ndị a.
3.Color Television Tubes: Na agba telivishọn tubes, terbium oxide na-etinye n'ọrụ na-emepụta red na green phosphor, nke na-eme ka agba ngosi site na-ekupụ ìhè mgbe egburu electrons.
Ihe onyonyo 4.X-ray:Terbium oxideenwere ike iji ya dị ka phosphor na ihuenyo X-ray iji gbanwee ụzarị X ka ọ bụrụ ìhè a na-ahụ anya, na-eme ka ọ dịrị ndị ọkachamara ahụike mfe ịhụ ihe oyiyi X-ray.
5.Magneto-optical Materials:Terbium oxideA na-arụ ọrụ na ihe magneto-optical, nke nwere ngwa na nchekwa data, ndị na-ahụ maka anya, na ngwaọrụ ndị ọzọ anya.
6.Glass na ceramik:Terbium oxideenwere ike itinye ya na iko na ihe seramiiki iji mepụta ihe nwere njirimara anya, dị ka agba agba ma ọ bụ nnabata UV.
7.Catalysts: Mgbe ụfọdụ,terbium oxideenwere ike iji ya mee ihe dị ka ihe na-akpata mmeghachi omume kemịkalụ, ọ bụ ezie na ngwa a adịghị adịkarị karịa iji ya na phosphor na ngwa anya.

Terbium oxide (Tb4O7)Ejikwa na mmepụta nketerbium metal, Ngwa anya iko, magneto-optical nchekwa, magnetik ihe, activators maka fluorescent powders, na mgbakwunye maka garnet, wdg
