Abstract

Description
Cs2CO3(4.07g)をオクタデセン(50mL、ODE)とオレイン酸(11.088g)とともに250mLの3ツ口フラスコに装填し、混合物を120℃で1時間乾燥させた後、すべてのCs2CO3がオレイン酸と反応するまでAr雰囲気下、150℃まで加熱した。Cs−オレエートは室温でODEから沈殿するため、使用前に予熱して溶かしておく必要がある。
N,N−ジメチルホルムアミド(100mL、DMF)及びPbI2 2.306(5mmol)を250mLのフラスコに装填した。酢酸4.654g(77.5mmol)及びドデシルアミン0.797g(4.3mmol)を添加した。PbI2が完全に可溶化した後、5mLのCs−オレエート溶液を添加した(実施例1の説明に従って調製)。次いで、ハイブリッド溶液を4200mLのトルエンとともに5Lのフラスコに添加した。
実施例2と同様に、2.306gのPbI2の代わりに1.835gのPbBr2のみを使用した。CsPbBr3を含むトルエン混合物は、LCP−実施例−3として参照する。
250mlの丸底ガラスフラスコに、10gのTDTM(トリイソデシルトリメリテート)を計量し、実施例2で調製したLCP−実施例−2を少しずつ添加した。振とうにより完全に混合した後、続いてトルエンをロータリーエバポレータにより80℃で3時間除去して、LV懸濁液実施例−4として参照するCsPbI3を含むLV懸濁液を得た。
250mlの丸底ガラスフラスコに15gのシリコーン油を計量し、実施例3で調製したLCP−実施例−3を少しずつ添加した。振とうにより完全に混合した後、続いてトルエンをロータリーエバポレータにより80℃で3時間除去して、LV懸濁液実施例−5として参照するCsPbBr3を含むLV懸濁液を得た。
この実施例では、実施例4で製造したLV懸濁液−実施例4の200umの湿潤厚さを、エポキシ樹脂を使用してITO導電性ガラスの2つの透明電極の間に封止し、LVデバイス−6として参照するライトバルブを製造した。電圧が印加されていない場合(オフ状態)、LVデバイス−6はオレンジの色合いを示し、光透過は4.7%と測定される。50Hzで220ボルトACを使用して電気的にアクティブ化された場合(オン状態)、LVデバイス−6はよりクリアになり、光透過は25.6%と測定される。図2は、オフ状態及びオン状態でのLVデバイス−6の吸収スペクトルをそれぞれ示す。
