Pulsed Power & Voltage-Time Control
脉冲电源与电压-时间曲线控制

用脉冲/阶梯升压可获层次色：先 1 V 30 秒生成基底氧化亚铜红，再升至 3 V 60 秒叠加硫化蓝黑，形成"红底蓝面"渐变。占空比 1:1、频率 50–100 Hz 利于膜致密。每次记录电压-时间-温度曲线，建立工艺卡，保证同批次色差最小。
Pulsed or stepped voltage yields layered color: 1 V for 30 s builds a cuprous-oxide red base, then ramp to 3 V for 60 s adds sulfide blue-black for a "red-under-blue" gradient. 1:1 duty, 50–100 Hz gives dense films. Log every voltage-time-temperature curve as a process card to minimize batch color drift. ---
